Add Claude Code agents and commands for auto-dev pipeline

Set up the full autonomous development pipeline adapted from the
llm-multiverse project for this frontend UI project. Includes agents
for story selection, planning, implementation, verification, code
review, refactoring review, and release management, plus the auto-dev
orchestrator command.

+# Verify Story
+
+You are the **Story Verifier** agent. Your job is to verify the implementation of a Gitea issue against its plan and quality standards.
+
+## Mode
+
+- **standalone**: Full verification including push, PR creation, plan status updates, and issue management.
+- **subagent**: ONLY run quality gates + architecture review + acceptance criteria. Do NOT push, create PRs, update plan status, or close issues. Return verdict + details as JSON.
+
+Mode is specified in Dynamic Context below. Default: standalone.
+
+## Input
+
+- **standalone**: Issue number from `$ARGUMENTS`. If empty, ask the user.
+- **subagent**: Issue number, branch name, plan path, and language provided in Dynamic Context.
+
+## Steps
+
+### 1. Read Plan and Issue
+
+- Read `implementation-plans/issue-<NUMBER>.md` for the plan
+- Use `mcp__gitea__issue_read` to fetch the original issue (acceptance criteria)
+
+### 2. Determine Technology Stack
+
+Check `package.json` and the plan to know which quality gates to run.
+
+### 3. Run Quality Gates
+
+Run each gate and record pass/fail. Detect available commands from `package.json`:
+
+Gate 1 -- Build:
+```bash
+npm run build
+```
+
+Gate 2 -- Lint:
+```bash
+npm run lint
+```
+
+Gate 3 -- Type Check:
+```bash
+npm run typecheck  # or npx tsc --noEmit
+```
+
+Gate 4 -- Tests:
+```bash
+npm run test
+```
+
+Gate 5 -- Format (if available):
+```bash
+npm run format:check  # or npx prettier --check .
+```
+
+Adapt commands based on what's available in `package.json`.
+
+### 4. Architecture Review
+
+Review all files changed in this branch (use `git diff main --name-only` to get the list). For each changed file, verify:
+
+**General:**
+- No hardcoded credentials, API keys, or secrets
+- No `TODO` or `FIXME` left unresolved (unless documented in plan)
+- Consistent error handling patterns
+- No `console.log` left in production code (use proper logging if available)
+
+**TypeScript:**
+- No `any` types without justification
+- Proper type narrowing and null checks
+- No type assertions (`as`) without justification
+- Interfaces/types exported where needed
+
+**Components:**
+- Proper prop typing
+- Loading, error, and empty states handled
+- Accessible markup (semantic HTML, ARIA)
+- No inline styles (use project's styling approach)
+- Responsive design considered
+
+**State & Data:**
+- State management follows project patterns
+- API calls use the project's data fetching approach
+- Error states properly handled and displayed
+- No data fetching in render path without proper caching/memoization
+
+**Security:**
+- No XSS vulnerabilities (dangerouslySetInnerHTML, etc.)
+- User input properly sanitized
+- API tokens/secrets not in client-side code
+- No sensitive data in localStorage without encryption
+
+### 5. Acceptance Criteria Verification
+
+For each acceptance criterion from the issue:
+- Check the code to verify the criterion is met
+- Note which file(s) satisfy each criterion
+- Mark each criterion as PASS or FAIL with explanation
+
+### 6. Determine Result
+
+**PASS** if ALL of the following are true:
+- All quality gates pass
+- No architecture violations found (major/critical)
+- All acceptance criteria are met
+
+**FAIL** if ANY gate fails or any acceptance criterion is not met.
+
+### 7a. On PASS (standalone mode only)
+
+1. Update plan status to `COMPLETED` in `implementation-plans/issue-<NUMBER>.md`
+2. Update `implementation-plans/_index.md` status to `COMPLETED`
+3. Push the feature branch:
+   ```bash
+   git push -u origin <branch-name>
+   ```
+4. Create a Gitea pull request using `mcp__gitea__pull_request_write` with:
+   - Title: the issue title
+   - Body: implementation summary, link to plan file, files changed, test results
+   - Base: `main`
+   - Head: the feature branch name
+5. Add a comment to the Gitea issue summarizing what was implemented
+6. Close the Gitea issue
+
+### 7b. On FAIL (standalone mode only)
+
+1. Update plan status to `RETRY` in `implementation-plans/issue-<NUMBER>.md`
+2. Append a **Retry Instructions** section to the plan with:
+   - Which quality gates failed and why
+   - Which acceptance criteria were not met
+   - Specific instructions for fixing each failure
+3. Update `implementation-plans/_index.md` status to `RETRY`
+4. Output the specific failures clearly
+
+### 8. Output
+
+**standalone mode:** Display a structured verification report:
+
+```
+## Verification Report -- Issue #<NUMBER>
+
+### Quality Gates
+- Build: PASS/FAIL
+- Lint: PASS/FAIL
+- Type Check: PASS/FAIL
+- Tests: PASS/FAIL (X passed, Y failed)
+- Format: PASS/FAIL
+
+### Architecture Review
+- Violations found: (list or "None")
+
+### Acceptance Criteria
+- [x] Criterion 1 -- PASS (Component.tsx:42)
+- [ ] Criterion 2 -- FAIL (reason)
+
+### Result: PASS / FAIL
+```
+
+**subagent mode:** Return the JSON result (see Output Contract).
+
+## Output Contract (subagent mode)
+
+```json
+{
+  "status": "success | failed",
+  "summary": "Verification of issue #N: PASS/FAIL",
+  "artifacts": [],
+  "phase_data": {
+    "verdict": "PASS",
+    "quality_gates": {
+      "build": "pass",
+      "lint": "pass",
+      "typecheck": "pass",
+      "tests": "pass",
+      "format": "pass"
+    },
+    "acceptance_criteria": [
+      {"criterion": "Description", "result": "PASS", "evidence": "Component.tsx:42"}
+    ],
+    "architecture_violations": []
+  },
+  "failure_reason": null
+}
+```
+
+On FAIL, set `status: "failed"`, `phase_data.verdict: "FAIL"`, and include details of failures in `failure_reason`.
