/**
* agent-session-runner.ts
*
* Streaming variant of runAgent wired to a VIBN agent_sessions row.
* After every LLM turn + tool call, it PATCHes the session in the VIBN DB
* so the frontend can poll (and later WebSocket) the live output.
*
* Key differences from runAgent:
* - Accepts an `emit` callback instead of updating job-store
* - Accepts an `isStopped` check so the frontend can cancel mid-run
* - Tracks which files were written/modified for the changed_files panel
* - Calls vibn-frontend's PATCH /api/projects/[id]/agent/sessions/[sid]
