Add Agent Manager for multi-agent orchestration

[marius-kilocode]

Adds a new Agent Manager panel for running multiple autonomous agent sessions in parallel.

Features:

• Adds an Agent Manager button to the kilo code sidebar
• Each agent is driven by a in process isolated kilo code cli binary
• Users can start multiple agent sessions in parallel in the same repository
• Start, stop, and remove sessions
• Session state managed via Jotai in webview

Notes:

• The parallel worktree integration is not part of this PR to keep it smaller
• Behind feature flag (AGENT_MANAGER_ENABLED) - dev mode only
• Agents run in full-auto mode without user confirmation, but user gets a notification
• Requires kilocode CLI to be installed (we validate this)
• We also validate for empty repositories
• All localizations are added

Pull request overview

This PR adds a multi-agent orchestration system called "Agent Manager" that enables running multiple autonomous AI agent sessions in parallel. Each agent is driven by an isolated Kilocode CLI process running in JSON mode, with state management handled via Jotai in the webview.

Key Changes:

• New Agent Manager panel accessible from the sidebar (behind AGENT_MANAGER_ENABLED feature flag)
• Complete webview UI with session management, message streaming, and real-time status updates
• Backend provider that spawns and manages CLI processes, parsing nd-json output
• Comprehensive test coverage for parser logic and state management

I tested it, and while there's definitely room for improvement, I think this is a good place to start with a first version. Great job!
