feat: CLI command to view crisis metrics summary (#136 )

New crisis/metrics.py: - CrisisEvent dataclass for individual events - log_event(): append to ~/.the-door/crisis-metrics.jsonl - load_events(): load last N days from JSONL - compute_summary(): aggregate by level, top indicators, sessions affected, daily average, peak day - MetricsSummary dataclass - format_summary(): human-readable report with bar chart - CLI: python3 -m crisis.metrics --summary/--json/--last 7d/--log Makefile targets: - make metrics — weekly summary report - make metrics-json — raw JSON export Closes #136
feat: cache offline crisis resources (refs #41 ) (#74 )

-
-Key behaviors:
-  - Escalation: LOW → HIGH in 3 messages triggers heightened awareness
-  - De-escalation: CRITICAL → LOW for 5+ messages allows stepping down
-  - Session state enriches the system prompt with trajectory context
-
-Usage:
-    from crisis.session_tracker import CrisisSessionTracker
-
-    tracker = CrisisSessionTracker()
-    tracker.record("I'm feeling down")
-    tracker.record("Things are really hard")
-    tracker.record("I can't go on anymore")  # escalation detected
-    print(tracker.get_prompt_context())
-    # "User has escalated from LOW to HIGH over 3 messages."

-When a Man Is Dying — Despair/Suicide Detection System
+DEPRECATED — Use crisis.detect instead.

-Standalone detection module that parses incoming text for
-despair and suicide indicators, classifies into tiers,
-and returns structured response with recommended actions.
+This module is a thin wrapper around crisis.detect for backward compatibility.
+All unique patterns have been merged into crisis/detect.py (see issue #40).

-Tiers:
-  LOW      — General sadness, stress, difficult times
-  MEDIUM   — Hopelessness, isolation, worthlessness
-  HIGH     — Active despair, mentions of death, "can't go on"
-  CRITICAL — Imminent risk, explicit intent, plan, method
-
-Integration:
-  Designed to work with crisis/ module from PR #4.
-  When crisis/ is available, uses it as the detection backend.
-  Falls back to internal detection when crisis/ is not present.
+This module will be removed in a future release.

+<h1>Focus Trap Manual Test</h1>
+<p>Open <code>index.html</code> in a browser, then run these checks:</p>
+
+<div class="test" id="test-1">
+  <strong>Test 1: Tab wraps to first element</strong><br>
+  1. Open safety plan modal<br>
+  2. Tab through all elements until you reach "Save Plan"<br>
+  3. Press Tab again → should wrap to close button (X)
+</div>
+
+<div class="test" id="test-2">
+  <strong>Test 2: Shift+Tab wraps to last element</strong><br>
+  1. Open safety plan modal<br>
+  2. Focus is on "Warning signs" textarea<br>
+  3. Press Shift+Tab → should wrap to "Save Plan" button
+</div>
+
+<div class="test" id="test-3">
+  <strong>Test 3: Escape closes modal</strong><br>
+  1. Open safety plan modal<br>
+  2. Press Escape → modal closes<br>
+  3. Focus returns to the button that opened it
+</div>
+
+<div class="test" id="test-4">
+  <strong>Test 4: Background not reachable</strong><br>
+  1. Open safety plan modal<br>
+  2. Try to Tab to the chat input behind the modal<br>
+  3. Should NOT be able to reach it
+</div>
+
+<div class="test" id="test-5">
+  <strong>Test 5: Click buttons close + restore focus</strong><br>
+  1. Open modal via "my safety plan" button<br>
+  2. Click Cancel → modal closes, focus on "my safety plan" button<br>
+  3. Open again, click Save → same behavior<br>
+  4. Open again, click X → same behavior
+</div>
