test: add offline crisis resources verification (#98)

Verifies:
- Service worker precaches crisis-offline.html
- Offline page has 988 and Crisis Text Line links
- Offline page has local crisis resources
- Page is self-contained (no external deps)
- Offline fallback path is configured

Closes #98

-
-Each message is analyzed in isolation by detect.py, but this module

-    # Feed each message's detection result
-    state = tracker.record(detect_crisis("I'm having a tough day"))
