docs: add guide for applying semantic commit format

Add SEMANTIC_COMMITS.md with instructions for rewriting commit history
to follow Conventional Commits format. Includes the exact commit messages
needed and steps for manual rebase.

The commits need to be rewritten as:
- fix(imports): for the langchain import fixes
- docs(timeout): for the timeout documentation

Automated tools cannot force-push, so maintainer needs to apply manually.

+# Semantic Commit Format for This PR
+
+## Current Situation
+
+This PR contains commits that need to be rewritten to follow Conventional Commits format for semantic-release compatibility.
+
+## Commits to Rewrite
+
+### Commit 1: 9439fe5
+**Current:** `Fix langchain import issues blocking tests`
+
+**Should be:**
+```
+fix(imports): update deprecated langchain imports to langchain_core
+
+Update imports from deprecated langchain.prompts to langchain_core.prompts
+across 20 files to fix test suite import errors. These changes address
+breaking API changes in newer langchain versions.
+
+Fixes #1015
+```
+
+**Type:** `fix` - Bug fix for test import errors
+**Scope:** `imports` - Changes affect import statements
+
+---
+
+### Commit 2: 323f26a  
+**Current:** `Add comprehensive timeout feature documentation`
+
+**Should be:**
+```
+docs(timeout): add comprehensive timeout configuration guide
+
+Add detailed documentation for FetchNode timeout feature including:
+- Configuration examples with different timeout values
+- Use cases for HTTP requests, PDF parsing, and ChromiumLoader
+- Graph integration examples
+- Best practices and troubleshooting guide
+
+The timeout feature was already implemented in the base code and this
+documentation helps users configure and use it effectively.
+
+Fixes #1015
+```
+
+**Type:** `docs` - Documentation changes only
+**Scope:** `timeout` - Related to timeout feature documentation
+

+
+## How to Apply (For Maintainer)
+
+Since automated tools can't force-push to rewrite history, the maintainer needs to manually rewrite these commits:
+
+### Option 1: Interactive Rebase
+```bash
+git rebase -i 6d13212
+# Mark commits 9439fe5 and 323f26a as 'reword'
+# Update commit messages with semantic format above
+# Force push: git push --force-with-lease
+```
+
+### Option 2: Squash and Rewrite
+```bash
+# Reset to initial commit
+git reset --soft 6d13212
+
+# Stage import fixes
+git add scrapegraphai/
+
+# Commit with semantic message
+git commit -m "fix(imports): update deprecated langchain imports to langchain_core
+
+Update imports from deprecated langchain.prompts to langchain_core.prompts
+across 20 files to fix test suite import errors. These changes address
+breaking API changes in newer langchain versions.
+
+Fixes #1015"
+
+# Stage documentation
+git add docs/
+
+# Commit with semantic message
+git commit -m "docs(timeout): add comprehensive timeout configuration guide
+
+Add detailed documentation for FetchNode timeout feature including:
+- Configuration examples with different timeout values
+- Use cases for HTTP requests, PDF parsing, and ChromiumLoader
+- Graph integration examples
+- Best practices and troubleshooting guide
+
+The timeout feature was already implemented in the base code and this

+
+Fixes #1015"
+
+# Force push
+git push --force-with-lease origin copilot/add-timeout-to-fetch-node
+```
