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.

 # Changelog
 
+## 0.5.4 — 2026-03-17
+
+- **Engineering review is always the full review now.** `/plan-eng-review` no longer asks you to choose between "big change" and "small change" modes. Every plan gets the full interactive walkthrough (architecture, code quality, tests, performance). Scope reduction is only suggested when the complexity check actually triggers — not as a standing menu option.
+- **Ship stops asking about reviews once you've answered.** When `/ship` asks about missing reviews and you say "ship anyway" or "not relevant," that decision is saved for the branch. No more getting re-asked every time you re-run `/ship` after a pre-landing fix.
+
+### For contributors
+
+- Removed SMALL_CHANGE / BIG_CHANGE / SCOPE_REDUCTION menu from `plan-eng-review/SKILL.md.tmpl`. Scope reduction is now proactive (triggered by complexity check) rather than a menu item.
+- Added review gate override persistence to `ship/SKILL.md.tmpl` — writes `ship-review-override` entries to `$BRANCH-reviews.jsonl` so subsequent `/ship` runs skip the gate.
+- Updated 2 E2E test prompts to match new flow.
+
 ## 0.5.3 — 2026-03-17
 
 - **You're always in control — even when dreaming big.** `/plan-ceo-review` now presents every scope expansion as an individual decision you opt into. EXPANSION mode recommends enthusiastically, but you say yes or no to each idea. No more "the agent went wild and added 5 features I didn't ask for."
