Release notes.

--parallel N fans one command into N independent runs, each in its own worktree.

Cold start down from 900 ms to 420 ms.

Interrupted runs now settle with exit code 2 instead of hanging.

Workspaces survive app restarts and resume where they left off.

Notification rules now apply per workspace, not per app.

Diff view no longer loses scroll position on re-render.

GET /v1/runs/:id/events supports Last-Event-ID resumption.

Idempotency-Key on POST /v1/runs.

Usage now rides on the run receipt instead of a nightly report.
