Adds GET /community/posts, GET /community/posts/{slug}, GET /community/feed.rss,
GET /community/local-feed, POST /community/posts, DELETE /community/posts/{slug},
POST /community/posts/{slug}/fork, and POST /community/posts/{slug}/fork-adapt (501 stub).
Wires init_community_store into main.py lifespan. 7 new tests; 115 total passing.
Replace hand-rolled feedback.py with make_feedback_router() from
circuitforge_core.api.feedback. Update tests to mount the shared
router on a minimal FastAPI app and mock at the core module level.
- feedback.py: add GET /feedback/status endpoint (returns {enabled: bool})
so frontend can probe on mount instead of optimistic-enable; remove
unused get_db import
- FeedbackButton.vue: probe /feedback/status on mount, start hidden;
drop redundant 503-hide path (status probe makes it redundant)
- pyproject.toml: declare requests>=2.31 (used by feedback.py Forgejo calls)
- tests/api/test_feedback.py: 7 tests — status endpoint (no-token, token,
demo mode), POST 503/403, happy path with mocked Forgejo, 502 on error
