fix(pull-request): add perfect mode with CodeRabbit auto-trigger strategy

Add section 7 (perfect mode) consistent with Vue skill. CodeRabbit
auto-triggers on push — manual ping only after 5 min timeout. Add
CodeRabbit wait polling to monitoring.md reference.

+When invoked with `--perfect`, run an outer convergence loop after the standard monitor loop (section 6) completes:
+
+```text
+REPEAT:
+  1. Wait for CodeRabbit          → CodeRabbit auto-triggers on every push. Poll for up to 5 min.
+                                    ONLY if no review appears after 5 min, post:
+                                    `@coderabbitai full review` as PR comment, then wait (see monitoring.md)
+  2. Run monitor loop (section 6) → fix all comments, resolve all threads, CI green
+  3. Run diff audit               → audit `git diff master...HEAD` for security, logic bugs,
+                                    data integrity, API design, performance issues
+  4. If audit has findings        → fix all, commit, push, GOTO 1
+  5. If 0 CodeRabbit comments AND 0 audit findings → STOP ✓

+## Wait for CodeRabbit after re-trigger
+
+When you post `@coderabbitai full review`, CodeRabbit replies "Full review triggered" immediately — but the actual review has **not started yet**. The `CodeRabbit: pass` status check is **stale** from the previous review. You must wait for the new review summary comment before declaring clean:
+
+```bash
+# Poll until CodeRabbit posts its new review summary (contains "Actionable comments")
+for i in $(seq 1 20); do
+  LATEST=$(gh api repos/$OWNER/$REPO/issues/$PR/comments \
+    --jq '[.[] | select(.user.login=="coderabbitai")] | sort_by(.created_at) | last | .body[0:200]')
+  if echo "$LATEST" | grep -qiE "actionable|no issues found|walkthrough"; then
+    echo "CodeRabbit review posted" && break
+  fi
+  sleep 30
+done
+```
+
+Only after this should you check for unresolved threads and declare clean.
