feat(my-deepagent): v0.4 — workflow generator UI + hot-reload + UX polish

브라우저에서 YAML 안 쓰고도 새 워크플로우 템플릿 만들기 + 즉시 등록.
+ /new.html / index.html / new-workflow.html / runs.html / conversation.html
의 nav·copy·empty-state 정비.

A. /new.html UX:
- 제목 "새 Run" → "워크플로우 실행 (고급)"
- 상단 info-box: "자유 대화는 여기가 아닙니다 → 메인 페이지"
- 모든 필드에 한 줄 hint
- Persona 오버라이드 <details> 접힘

B. Nav 재정렬 (5 페이지):
- "대화" nav-primary, 나머지 nav-secondary (작고 dim)

C. 메인 안내 + CSS:
- 메인 / 에 "👋 my-deepagent" info-box 추가
- .info-box / .nav-primary / .nav-secondary / .wf-* 신규 스타일

D. Workflow hot-reload:
- api/deps.py get_workflows 가 매 요청 mtime 튜플 검사 후 변경 시 reload
- lifespan 도 user dir 포함하도록 _load_workflows_combined

E. Workflow generator:
- POST /api/workflows: CreateWorkflowRequest → WorkflowTemplate validate →
  <data_dir>/workflows/<name>@<version>.yaml 저장.  중복 409, validation 422.
- static/new-workflow.html: 기본 정보 / Roles / Phases / YAML preview
- app.js bootstrapWorkflowGenerator: capability chip 토글, role select 동적,
  실시간 YAML preview, XSS 정책 유지

테스트 (test_workflow_generator.py, 7 신규):
- 페이지 200 + 마크업
- POST happy / 422 (empty roles) / 422 (unknown role) / 409 (dup)
- GET hot-reload after POST
- GET hot-reload after external file drop

게이트:
- ruff / format / mypy: PASS (142 source files)
- pytest -q --ignore=tests/integration/test_e2e_workflow.py
  --ignore=tests/integration/test_openrouter_smoke.py: 709 passed (+7 신규)
- 라이브 smoke: / / new.html / new-workflow.html 모두 200, screenshot OK

 ## [Unreleased]
 
+### Added
+- **v0.4 — Workflow generator UI + hot-reload + UX polish**.  사용자가 직접
+  YAML 을 작성하지 않고도 브라우저에서 새 워크플로우 템플릿을 만들고 즉시
+  실행할 수 있도록 함.  메인 페이지 / new.html / runs.html / new-workflow.html
+  의 nav · copy · empty-state 도 동시에 정비.
+  - **A — `/new.html` UX 패치** (HTML/CSS only):
+    - 제목 "새 Run 시작" → "워크플로우 실행 (고급 기능)".
+    - 상단 `info-box`: "자유 대화는 여기가 아닙니다 → 메인 페이지" 안내 +
+      "+ 템플릿 만들기" 링크.
+    - 모든 필드에 한 줄 hint (예: `repo 절대경로 — 작업할 git 저장소 위치`).
+    - Persona 오버라이드를 `<details>` 접힘 상태로 → 첫 사용자가 압도되지
+      않도록.
+  - **B — nav 재정렬** (`/`, `/runs.html`, `/new.html`, `/run.html`,
+    `/conversation.html`):
+    - "대화" 가 `nav-primary` (큰 폰트 + 진한 색).
+    - "Runs" / "워크플로우 실행" / "+ 템플릿 만들기" 는 `nav-secondary`
+      (작은 폰트 + 65% opacity, hover 시 100%).
+  - **C — 메인 페이지 안내** + CSS:
+    - 메인 `/` 에 `info-box` 추가 ("👋 my-deepagent — OpenRouter 가성비 모델로
+      돌아가는 Claude Code 스타일 멀티턴 에이전트").
+    - `style.css` 에 `.info-box`, `.nav-primary`/`.nav-secondary`,
+      `.wf-row-card`, `.wf-chip` 등 신규 스타일 추가.
+  - **D — Workflow hot-reload**:
+    - `api/deps.py` 의 `get_workflows` 가 매 요청 시
+      `_workflow_dir_signature(config)` (seed + user 디렉터리의 mtime 튜플)
+      을 계산해 cached signature 와 다르면 `load_combined_workflows` 재호출.
+      파일 watcher / inotify 없이 stat 만으로 충분 (디렉터리가 작음).
+    - lifespan 의 `_load_seed_workflows` 도 `_load_workflows_combined` 로
+      교체해 user dir 첫 부팅 시도 자동 로드.
+  - **E — Workflow generator UI**:
+    - **API**: `POST /api/workflows` 신설.  Body = `CreateWorkflowRequest`
+      pydantic (name / version / description / roles / phases / default_gates /
+      max_total_budget_usd).  `WorkflowTemplate.model_validate` 로 strict
+      검증 → 실패 시 422 (loc:msg 포맷으로 평탄화).  성공 시
+      `<data_dir>/workflows/<name>@<version>.yaml` 에 YAML 저장 (`yaml.safe_dump
+      allow_unicode=True, sort_keys=False`).  중복 (name, version) 은 409.
+    - **HTML**: `static/new-workflow.html` (신규).  기본 정보 → Roles →
+      Phases → YAML 미리보기 → 저장 버튼.
+    - **JS**: `app.js` 에 `bootstrapWorkflowGenerator` 와 `WF_STATE` 추가.
+      Role 별 capability 를 chip 형태로 클릭 토글, Phase 의 role 셀렉트는
+      현재 Role 목록에서 동적으로 생성.  실시간 YAML preview.  XSS 정책
+      유지 (모든 사용자 입력은 textContent).
+  - **신규 테스트** (`tests/integration/test_workflow_generator.py`, 7 케이스):
+    - `/new-workflow.html` 200 + 마크업
+    - POST happy path → yaml 파일 영속 + path / name / version 검증
+    - POST roles=[] → 422
+    - POST phase.role 미존재 → 422 + 메시지에 role id 포함
+    - POST duplicate (name, version) → 409
+    - GET hot-reload: POST 후 새 항목이 GET 응답에 등장
+    - GET hot-reload: 외부에서 YAML 파일 직접 떨궈도 mtime 으로 감지
+
