feat: crisis overlay full Tab cycle + Escape dismiss (#95)

Three fixes:
1. Focus lands on Call 988 link on open (not disabled dismiss button)
2. Focus trap catches escaped focus outside overlay
3. Escape key closes overlay, returns focus to chat input

Closes #95

-Session-level crisis tracking and escalation for the-door (P0 #35).
-
-Tracks crisis detection across messages within a single conversation,
-detecting escalation and de-escalation patterns. Privacy-first: no
-persistence beyond the conversation session.
-
-Each message is analyzed in isolation by detect.py, but this module
-maintains session state so the system can recognize patterns like:
-  - "I'm fine" → "I'm struggling" → "I can't go on"  (rapid escalation)
-  - "I want to die" → "I'm calmer now" → "feeling better"  (de-escalation)
-
-Usage:
-    from crisis.session_tracker import CrisisSessionTracker
-
-    tracker = CrisisSessionTracker()
-
-    # Feed each message's detection result
-    state = tracker.record(detect_crisis("I'm having a tough day"))
-    print(state.current_level)  # "LOW"
-    print(state.is_escalating)  # False
-
-    state = tracker.record(detect_crisis("I feel hopeless"))
-    print(state.is_escalating)  # True (LOW → MEDIUM/HIGH in 2 messages)
-
