feat(scribe): snippet management UI + REST routes; embed snippets on create

Step 6 of the Drafter recall milestone (#227): a human-facing surface for the reusable-code snippets that agents record via MCP, plus the REST API behind it. Backend embeds snippets inline on create/update so they're recallable immediately, not only after a restart. Backend: - routes/snippets.py: GET/POST /api/snippets, GET/PATCH/DELETE /api/snippets/<id>. Share-aware per rule #78 (get_note_for_user + can_write_note), writes performed as the owner; list owner-scoped — mirrors routes/notes.py. Registered in app.py. - services/snippets.py: embed on create/update via a _embed_snippet fire-and-forget helper, covering BOTH the MCP tool and the REST route by construction. A snippet's value is immediate recall, so it can't wait for the startup-only backfill (see issue: MCP create path doesn't embed inline for notes/tasks generally). - tests/test_routes_snippets.py: structural registration + handler/service contract + PATCH-field ↔ update_snippet-kwarg parity (rule #33). Frontend (Vue 3 + TS): - api/snippets.ts: typed client, modeled on api/systems.ts. - views: SnippetListView (search, skeleton/empty/error states), SnippetDetailView (read + copy-to-clipboard, ConfirmDialog delete), SnippetEditorView (create/edit all fields, Ctrl/Cmd+S, Esc, autofocus, validation). v1 quality per rules #24/#27. - router: /snippets, /snippets/new, /snippets/:id, /snippets/:id/edit. - NoteType union widened to include 'snippet'; Snippets nav link added to AppHeader (desktop pill bar + mobile menu). - Design system: Moss --color-action-primary for action buttons, accent --color-primary reserved for tags/brand (Hybrid rule); focus rings; JetBrains Mono for code/name/signature/location.
