Work On Issues

Sequential autopilot over implement + code-review, built to stop rather than guess whenever a ticket isn't actually ready. Read CONTEXT.md's "## Engineering Setup" section first.

Steps

1. Ask the mode up front, once: stop after each ticket for review, or keep going through every ready ticket unattended? Don't assume — a wrong assumption here means either annoying interruptions or several tickets built on a bad early decision before anyone notices.
