feat(code-review): add HALT guards, batch option, defer reason, final summary

Add strong HALT guards after decision-needed and patch menus to prevent
auto-progression. Add batch-apply option 0 for >3 patch findings. Prompt
for defer reason and append to story file and deferred-work.md. Show
boxed final summary with counts. Polish clean-review shortcut in triage.

 If `decision_needed` findings exist, present each one with its detail and the options available. The user must decide — the correct fix is ambiguous without their input. Walk through each finding (or batch related ones) and get the user's call. Once resolved, each becomes a `patch`, `defer`, or is dismissed.
 
+If the user chooses to defer, ask: Quick one-line reason for deferring this item? (helps future reviews): — then append that reason to both the story file bullet and the `{deferred_work_file}` entry.

+- **Option 0** (only when >3 findings): Apply all non-controversial patches without per-finding confirmation. Skip any finding that requires judgment. Present a summary of changes made and any skipped findings.

 - **Walk through each**: Present each finding with full detail, diff context, and suggested fix. After walkthrough, re-offer the applicable options above.
