feat: plan files always show review status (v0.11.1.1) (#345)

* feat: plan files always show review status via preamble footer

Add Plan Status Footer to generateCompletionStatus() in the preamble.
When in plan mode before ExitPlanMode, Claude writes a GSTACK REVIEW
REPORT section to the plan file — either populated from review logs
or a "NO REVIEWS YET" placeholder. Skips if a review skill already
wrote a richer report.

* chore: bump version and changelog (v0.11.1.1)
