Post-merge closeout for #854 (surface cigen info in MCP output). Adds the retrospective and flips the plan Status Locked->Complete (removes the .scope-lock sidecar). Docs-only.

Pull request overview

Closes out the documentation work from #854 by adding a retrospective and marking the corresponding implementation plan as complete (including removing the scope-lock sidecar), keeping the docs/plans workflow consistent after merge.

Changes:

  • Added a retrospective documenting what shipped, what gates caught, lessons, and follow-ups for #854.
  • Marked the implementation plan status as Complete with a completion timestamp.
  • Removed the .scope-lock sidecar file now that the plan is complete.
