feat: inline /office-hours — no more "another window" (v0.11.3.1) (#352)

* feat: inline /office-hours invocation — no more "another window"

BENEFITS_FROM now uses read-and-follow pattern (same as /autoplan) to run
/office-hours inline. Removes handoff note save infrastructure from
plan-ceo-review template. Keeps handoff note check for backward compat.

* chore: bump version and changelog (v0.11.3.1)
