Jason Woltje 85135779c6 fix: add mission detection to session hooks
Patches session-start.sh to detect active orchestrator missions
and print a banner with phase, milestone, progress, and scratchpad.
Patches session-end.sh to record session results in mission.json.

These were in the mosaic-bootstrap template but not yet applied
to this project's existing hooks.
