whqreza 9e848f535f feat(bot): add DeepSeek crisis fallback engine for Jev failure and remove difflib heuristics
- Add app/fallback_matcher.py for intelligent crisis entity matching with token and latency observability
- Route Jev failure/timeouts in app/matching.py to DeepSeek fallback engine
- Handle MatchingFailureError defensively in handlers/__init__.py with honest error message
- Enforce strict 'new' entity status in handlers/quote.py and implement defensive get_or_create on commit
- Clean up app/resolve.py to eliminate difflib and character ratio heuristics
- Pass all smoke tests (59/59), fallback matching tests (15/15), and matching unit tests (13/13)

"""Unit and integration tests for DeepSeek crisis fallback matching.
Covers:
1. Jev failure -> jev.failure observability event + DeepSeek fallback invocation.
2. DeepSeek fallback results mapping: exact, ambiguity, new (with inferred category).
3. Defensive failure guard: DeepSeek network/HTTP/JSON failure raises MatchingFailureError.
4. quote.py resolve_payload: respects new, binds exact, populates ambiguity, zero difflib.
5. quote.py commit: defensive get_or_create pattern prevents 409 duplicate errors.
