Enhance .cursor documentation and workflows

Updated the README.md to reflect new skill commands and improved descriptions for various workflows, including the addition of new skills like /test-spec, /code-review, and /release. Enhanced clarity on session boundaries and flow resolutions in the auto-chaining process.

Removed the implementer agent file as it is no longer needed. Updated coderule and meta-rule documents to enforce stricter testing and implementation standards, ensuring real results are produced rather than simulated ones.

Revised the autodev flow documentation to include a new release step and clarified the retrospective process. Adjusted the testing rules to specify coverage thresholds for critical paths.

+
+### Change Summary
+
+| Component | Tickets | Type |
+|-----------|---------|------|
+| {component} | TKT-001, TKT-002 | feature / fix / breaking / security |
+
+### Rollback Plan
+
+- Previous version: `{previous-version}` (registry digest: `{sha}`)
+- Rollback script: `scripts/deploy.sh --rollback`
+- Rollback target verified pullable: yes / no
+- Rollback target verified bootable in target env: yes / no
+
+### Restrictions / Approvals
+
+- Change-window restrictions: {none | description}
+- Manual approvals required: {none | reference to approval file}
+
+### Tracker State at Gate
+
+- Tickets in scope: {N}
+- Tickets blocking release: {0 — list any}
+
+## Strategy Select (Phase 2)
+
+- Recommended: {strategy} — reasoning
+- Chosen: {strategy} — reasoning (if differs from recommended)
+
+## Execute (Phase 3)
+
+- Start: {timestamp}
+- End: {timestamp}
+- Exit code: {0 / non-zero}
+
+```
+<scripts/deploy.sh stdout/stderr stream, with timestamps>
+```
+
+## Smoke Test (Phase 4)
+
+- Mode: {/test-run --prod-smoke | manual smoke set}
+- Start: {timestamp}
+- End: {timestamp}
+
+| Test | Result | Notes |
+|------|--------|-------|
+| {name} | Pass / Fail | response time, status, etc. |
+
+## Watch Window (Phase 5)
+
+- Duration: {minutes}
+- Cadence: {minutes per poll}
+- Backend: {observability source — Prometheus, CloudWatch, Datadog, etc.}
+
+| T+min | error_rate | rps | p99_latency | saturation | health | notes |
+|-------|------------|-----|-------------|------------|--------|-------|
+| 0 | … | … | … | … | OK | … |

+
+### Threshold breaches
+
+- {None | "p99 latency 1.7× baseline at T+8 — soft breach, user accepted continuation"}
+
+## Commit or Rollback (Phase 6)
+
+### If Released
+
+- Tracker tickets moved: {list}
+- Git tag pushed: {tag} → {sha}
+- Retrospective scheduled: yes — {/retrospective --cycle-end output path}
+
+### If Rolled-Back
+
+- Trigger: {auto / user-elected}
+- Reason: {phase + one-line cause}
+- Rollback start: {timestamp}
+- Rollback end: {timestamp}
+- Post-rollback smoke: pass / fail
+- Tracker tickets moved back: {list}
+- Incident retrospective scheduled: yes — {/retrospective --incident output path}
+
+### If Aborted
+
+- Phase that aborted: {1 / 2 / 3 / 4 / 5}
+- Reason: {one-line cause}
+- No live-system changes attempted: yes / no (if live changes, document under Phase 3 above and treat as Rolled-Back instead)
+
+## Lessons (one-liners; full incident retro if Rolled-Back / Released-with-override)
+
+- {Optional: short one-liner observations the operator wants the next /retrospective to consider}
