Integrates ollama-ai-provider-v2 to enable running AI models locally
through Ollama without requiring API keys.

Changes:
- Add ollama-ai-provider-v2 dependency
- Implement Ollama provider in aiService.ts with lazy loading
- Add OllamaProviderOptions type for future extensibility
- Support Ollama model display formatting (e.g., llama3.2:7b -> Llama 3.2 (7B))
- Update providers.jsonc template with Ollama configuration example
- Add comprehensive Ollama documentation to models.md
- Add unit tests for Ollama model name formatting

Ollama is a local service that doesn't require API keys. Users can run
any model from the Ollama Library (https://ollama.com/library) locally.

Example configuration in ~/.cmux/providers.jsonc:
{
  "ollama": {
    "baseUrl": "http://localhost:11434"
  }
}

Example model usage: ollama:llama3.2:7b

-Currently we support the Sonnet 4 models and GPT-5 family of models:
+cmux supports multiple AI providers through its flexible provider architecture.
+
+### Supported Providers
+
+#### Anthropic (Cloud)
+
+Best supported provider with full feature support:
 
 - `anthropic:claude-sonnet-4-5`
 - `anthropic:claude-opus-4-1`
+
+#### OpenAI (Cloud)
+
+GPT-5 family of models:
+
 - `openai:gpt-5`
 - `openai:gpt-5-pro`
 - `openai:gpt-5-codex`
 
-And we intend to always support the models used by 90% of the community.
-
-Anthropic models are better supported than GPT-5 class models due to an outstanding issue in the
-Vercel AI SDK.
+**Note:** Anthropic models are better supported than GPT-5 class models due to an outstanding issue in the Vercel AI SDK.
 
 TODO: add issue link here.
+
+#### Ollama (Local)
+
+Run models locally with Ollama. No API key required:
+
+- `ollama:llama3.2:7b`
+- `ollama:llama3.2:13b`
+- `ollama:codellama:7b`
+- `ollama:qwen2.5:7b`
+- Any model from the [Ollama Library](https://ollama.com/library)
+
+**Setup:**
+
+1. Install Ollama from [ollama.com](https://ollama.com)
+2. Pull a model: `ollama pull llama3.2:7b`
+3. Configure in `~/.cmux/providers.jsonc`:
+
+```jsonc
+{
+  "ollama": {
+    // Default configuration - Ollama runs on localhost:11434
+    "baseUrl": "http://localhost:11434"
+  }
+}
+```
+
+For remote Ollama instances, update `baseUrl` to point to your server.
+
+### Provider Configuration
+
+All providers are configured in `~/.cmux/providers.jsonc`. See example configurations:
+
+```jsonc
+{
+  "anthropic": {
+    "apiKey": "sk-ant-..."
+  },
+  "openai": {
+    "apiKey": "sk-..."
+  },
+  "ollama": {
+    "baseUrl": "http://localhost:11434"  // Default - only needed if different
+  }
+}
+```
+
+### Model Selection
+
+Use the Command Palette (`Cmd+Shift+P`) to switch models:
+
+1. Open Command Palette
+2. Type "model"
+3. Select "Change Model"
+4. Choose from available models
+
+Models are specified in the format: `provider:model-name`

Adds comprehensive integration tests for Ollama provider to verify tool
calling and file operations work correctly with local models.

Changes:
- Add tests/ipcMain/ollama.test.ts with 4 test cases:
  * Basic message sending and response
  * Tool calling with bash tool (gpt-oss:20b)
  * File operations with file_read tool
  * Error handling when Ollama is not running
- Update setupWorkspace() to handle Ollama (no API key required)
- Update setupProviders() type signature for optional baseUrl
- Add Ollama installation and model pulling to CI workflow
- Configure CI to run Ollama tests with gpt-oss:20b model

The tests verify that Ollama can:
- Send messages and receive streaming responses
- Execute bash commands via tool calling
- Read files using the file_read tool
- Handle connection errors gracefully

CI Setup:
- Installs Ollama via official install script
- Pulls gpt-oss:20b model for tests
- Waits for Ollama service to be ready before running tests
- Sets OLLAMA_BASE_URL environment variable for tests

Cache Ollama models between CI runs to speed up integration tests.
The gpt-oss:20b model can be large, so caching saves significant time
on subsequent test runs.

Cache key: ${{ runner.os }}-ollama-gpt-oss-20b-v1

- Make cache keys more generic and future-proof
- Cache Ollama binary separately for instant cached runs
- Update model examples to popular models (gpt-oss, qwen3-coder)

Changes:
- Split Ollama caching into binary + models for better performance
- Only install Ollama if binary is not cached (saves time)
- Update docs to reference gpt-oss:20b, gpt-oss:120b, qwen3-coder:30b

- Fixed model string parsing to handle colons in model IDs (e.g., ollama:gpt-oss:20b)
  Split only on first colon instead of all colons
- Added Ollama compatibility mode (strict) for better API compatibility
- Fixed baseURL configuration to include /api suffix consistently
  Updated test setup, config template, docs, and CI
- Fixed test assertions to use extractTextFromEvents() helper
  Tests were incorrectly calling .join() on event objects instead of extracting delta text
- Removed test concurrency to prevent race conditions
  Sequential execution resolves stream-end event timing issues
- Updated file operations test to use README.md instead of package.json
  More reliable for test workspace environment

All 4 Ollama integration tests now pass consistently (102s total runtime)

- Remove unused modelString import from ollama.test.ts
- Use consistent indexOf() pattern for provider extraction in streamMessage()
  Ensures model IDs with colons are handled uniformly throughout codebase

Key improvements:
- Combined binary, library, and model caching into single cache entry
  Previously: separate caches for binary and models
  Now: /usr/local/bin/ollama + /usr/local/lib/ollama + /usr/share/ollama

- Fixed model cache path from ~/.ollama/models to /usr/share/ollama
  Models are stored in system ollama user's home, not runner's home

- Separated installation from server startup
  Install step only runs on cache miss and includes model pull
  Startup step always runs but completes in <5s with cached models

- Optimized readiness checks
  Install: 10s timeout, 0.5s polling (only on cache miss)
  Startup: 5s timeout, 0.2s polling (every run, with cache hit)

- Added cache key based on workflow file hash
  Cache invalidates when workflow changes, ensuring fresh install if needed

Expected timing:
- First run (cache miss): ~60s (download + install + model pull)
- Subsequent runs (cache hit): <5s (just server startup)
- Cache size: ~13GB (gpt-oss:20b model)

Testing: Verified locally that Ollama starts in <1s with cached models

Subject: [PATCH 11/36] =?UTF-8?q?=F0=9F=A4=96=20feat:=20add=20multi-patter?=
 =?UTF-8?q?n=20lookup=20for=20Ollama=20model=20context=20limits?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes context limit display for Ollama models like ollama:gpt-oss:20b.

Problem:
- User model string: ollama:gpt-oss:20b
- Previous lookup: gpt-oss:20b (stripped provider)
- models.json key: ollama/gpt-oss:20b-cloud (LiteLLM convention)
- Result: Lookup failed, showed "Unknown model limits"

Solution:
Implemented multi-pattern fallback lookup that tries:
1. Direct model name (claude-opus-4-1)
2. Provider-prefixed (ollama/gpt-oss:20b)
3. Cloud variant (ollama/gpt-oss:20b-cloud) ← matches!
4. Base model (ollama/gpt-oss) as fallback

Benefits:
- Works automatically for all Ollama models in models.json
- Zero configuration required
- Backward compatible with existing lookups
- No API calls needed (works offline)

Testing:
- Added 15+ unit tests covering all lookup patterns
- Verified ollama:gpt-oss:20b → 131k context limit
- All 979 unit tests pass

Models that now work:
- ollama:gpt-oss:20b → ollama/gpt-oss:20b-cloud (131k)
- ollama:gpt-oss:120b → ollama/gpt-oss:120b-cloud (131k)
- ollama:llama3.1 → ollama/llama3.1 (8k)
- ollama:deepseek-v3.1:671b → ollama/deepseek-v3.1:671b-cloud
- Plus all existing Anthropic/OpenAI models

- Download only the Ollama binary (no system service installation)
- Use 'ollama start' instead of 'ollama serve'
- Cache binary and models separately for better cache efficiency
- Models now naturally go to ~/.ollama (no sudo/copying needed)
- Removed complex model copying logic from cache miss path
- Simplified workflow - Ollama server starts in setup action

Benefits:
- Cache works correctly (models in user home, not system location)
- Faster warm cache (<1s vs ~60s)
- No sudo operations needed
- Matches proven pydantic/ollama-action approach

Previously, setup-ollama action pulled models sequentially during setup.
Now tests pull models idempotently in beforeAll hook, enabling:

- Better parallelism across test jobs
- Idempotent model pulls (multiple tests can check/pull safely)
- Shared model cache across parallel test runners
- Ollama handles deduplication when multiple pulls happen simultaneously

Changes:
- Remove model input and pull logic from setup-ollama action
- Add ensureOllamaModel() helper to check if model exists and pull if needed
- Call ensureOllamaModel() in beforeAll hook before tests run
- Bump beforeAll timeout to 150s to accommodate potential model pull
- Simplify cache key to 'ollama-models-v2' (model-agnostic)

Consolidates two instances of provider name extraction logic into a
single helper function. Both createModel() and streamMessage() were
duplicating the logic to parse provider names from model strings.

The helper properly handles Ollama model IDs with colons (e.g.,
"ollama:gpt-oss:20b" -> "ollama") by splitting only on the first colon.

Further eliminates duplication by having parseModelString return both
the provider name and model ID as a tuple [providerName, modelId].

This removes the remaining duplicated logic:
- modelString.slice(colonIndex + 1) in createModel()
- modelString.indexOf(":") check logic

Both call sites now use destructuring to get the parts they need.

Separates Ollama integration tests from main integration test suite:

**New Job: ollama-test**
- Dedicated job for Ollama-specific tests
- Sets up Ollama binary and model cache
- Runs only tests/ipcMain/ollama.test.ts
- Uploads coverage with 'ollama-tests' flag

**Updated Job: integration-test**
- Removed Ollama setup steps
- Excludes ollama.test.ts via --testPathIgnorePatterns
- Removed OLLAMA_BASE_URL env var
- Faster execution without Ollama dependencies

Benefits:
- Better parallelism (Ollama tests run independently)
- Clearer separation of concerns
- Main integration tests complete faster
- Ollama-specific caching isolated to one job

Simplifies CI by using an explicit environment variable instead of
path filtering:

**Test Changes:**
- Ollama tests now require both TEST_INTEGRATION=1 and TEST_OLLAMA=1
- Uses `describeOllama` that checks `process.env.TEST_OLLAMA === '1'`
- Auto-skips when TEST_OLLAMA is not set (no manual filtering needed)

**CI Changes:**
- `integration-test` job: runs all tests, Ollama tests skip automatically
- `ollama-test` job: sets TEST_OLLAMA=1 to enable Ollama tests
- Removed `--testPathIgnorePatterns` (no longer needed)
- Cleaner and more explicit test gating

Benefits:
- Simpler CI configuration (no path filtering)
- Consistent pattern with TEST_INTEGRATION
- Easy to run Ollama tests locally: TEST_INTEGRATION=1 TEST_OLLAMA=1 bun x jest tests/ipcMain/ollama.test.ts

Quiets verbose output from Ollama integration tests:

**CI Changes:**
- Added `--silent` flag to jest command (suppresses per-test output)

**Test Changes:**
- Removed `console.log` statements from `ensureOllamaModel()`
- Changed stdio from 'inherit' to 'pipe' to capture output silently
- Still capture stderr for error reporting if pull fails
- Add explanatory comments about silent mode

This dramatically reduces CI log verbosity while maintaining error visibility.

Reduces log spam in CI by mocking console.log and console.warn during
Ollama integration tests. The test output was showing 426+ console
statements including:
- Tokenizer warnings for unknown Ollama models
- Service logs from initStateManager and aiService
- Tool configuration logs

Changes:
- Add console.log/console.warn spies in beforeAll (CI only)
- Restore console in afterAll
- Only active when process.env.CI is set

This makes CI logs readable while preserving local dev debugging.
