Show the recap on Review and the carry-forward on Planning

The Review screen renders the reviewer's one-line recap (quiet pending
line, then the recap); the Planning screen renders last session's
carry-forward as a 'Last time: …' one-liner, mirroring the knowledge
indicator. Updates the README Status section for M7.

 ## Status
 
+M7 (reflection): when a session ends, a fourth AI role — the reviewer —
+reflects on it, read against your recent sessions, and produces two short
+lines: a recap shown on the Review screen, and a carry-forward takeaway that
+grounds the coach the next time you plan. It runs once asynchronously on
+entering Review, never blocks the End button, and degrades gracefully — with
+no backend (or a slow/failed call) Review and Planning behave exactly as
+before. The carry-forward is snapshot-persisted (latest-wins) and composes
+into the coach's grounding; the reflection lines are short and cross the wire
+by design, while the knowledge profile still does not.
+
 M6 (knowledge port): the planning coach now sharpens intents against who you
 actually are. A single profile file (`~/.antidrift/knowledge.md`, overridable
 via `ANTIDRIFT_KNOWLEDGE_FILE`) holds your standing context — priorities,
