/**
 * 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]
