feat: always-full eng review + ship review gate persistence (v0.5.4) (#135)

Remove SMALL/BIG CHANGE menu from /plan-eng-review — every plan gets the
full interactive review. Scope reduction is now proactive (only when
complexity check triggers) rather than a menu item.

Add review gate override persistence to /ship — when the user says "ship
anyway" or "not relevant", that decision is saved to the branch's
reviews.jsonl so subsequent /ship runs don't re-ask.
