feat: Claude Code Monitor — lanes, pipelines and a merged workspace

Browse Source 
Internal SmartGift build of a Claude Code monitoring dashboard.

Lanes: a durable unit of parallel agent work, one per working directory,
tracked across session restarts. Managed lanes are git worktrees the
dashboard provisions and can reset or remove behind a three-check destroy
guard and a counted preflight; adopted lanes are directories you already
own and are never destroyable.

Pipelines: a lane moves through pipeline stages. A stage the agent declares
with evidence renders green; a stage inferred from the tool-event stream
renders dashed amber and never counts as done. Detection is forward-only
within a 30-minute window, and never writes the declared stage.

Workspace: one page at /run with a lane grid, the selected lane's pipeline,
and a full Claude console behind a disclosure.

/**
* @file Main extension file for Claude Code Agent Monitor VSCode extension
* Sets up the extension, registers commands, and manages the status bar item.
* Implements a dynamic dashboard view that checks for active servers on ports 5173 and 4820.
* Provides real-time status updates in the sidebar and status bar with background polling.
