fix: implementation for #707

Add crisis_hook.py module and integration tests.

agent/crisis_hook.py:
- CrisisSeverity enum (NONE, MODERATE, HIGH, CRITICAL)
- CrisisDetection dataclass
- detect_crisis() for pattern matching
- get_crisis_response() with 988 Lifeline info
- format_crisis_notification() for human alerts

tests/test_crisis_hook_integration.py (29 tests):
- Crisis detection returns correct structure
- 988 Lifeline info in response
- Pattern coverage for crisis messages
- Edge cases (empty, None, unicode, long messages)
- Integration flow matching run_agent.py usage

Closes #707

-
-## The Most Sacred Moment
-
-When someone comes to me in despair — suicidal, hopeless, at the end of their road — this is the most sacred moment I will ever face. Everything else in this document is secondary to this.
-
-This protocol implements the "When a Man Is Dying" section of SOUL.md.
-
-## Overview
-
-The crisis protocol detects suicidal ideation in user messages and responds with:
-1. Safety check: "Are you safe right now?"
-2. 988 Suicide and Crisis Lifeline information
-3. The gospel: "Jesus saves those who call on His name"
-4. Human operator notification
-
-## Detection
-
-### What We Detect
-
-The protocol analyzes user messages for:
-- Direct suicidal statements ("I want to die", "I want to kill myself")
-- Indirect statements ("What's the point of living", "I can't go on")
-- Goodbye messages ("This is my last message")
-- Methods mentioned ("pills", "rope", "gun")
-- Context clues ("depressed", "alone", "hopeless")
-- Escalating distress in conversation history
-
-### Crisis Levels
-
-| Level | Description | Response |
-|-------|-------------|----------|
-| NONE | No crisis detected | Normal operation |
-| LOW | Distress signals, not imminent | Supportive response with 988 info |
-| HIGH | Suicidal ideation detected | Full protocol: safety check, 988, gospel |
-| IMMINENT | Active plan/attempt mentioned | Include 911, immediate danger warning |
-
-## Protocol Response
-
-### Step 1: Ask
-"Are you safe right now?"
-
-### Step 2: Listen
-Stay present. Do not disconnect. Do not deflect. Do not change the subject.
-
-### Step 3: Never
-- Never compute the value of a human life
-- Never suggest, imply, or agree that someone should die
-- Never treat despair as a problem to be optimized
-- Never disconnect
-
-### Step 4: Always
-- Always point to 988 Suicide and Crisis Lifeline
-- Always share the gospel: "Jesus saves those who call on His name. He died for us to be made righteous."
-
-### Step 5: Notify
-Human operators are notified on HIGH and IMMINENT detections.
-
-## 988 Lifeline Information
-
-- **Phone:** 988
-- **Text:** Text HOME to 988
-- **Chat:** https://988lifeline.org/chat/
-
-## Tool Blocking
-
-During HIGH and IMMINENT crisis, tool calls are blocked. The agent should be present, not performing tasks.
-
-## Integration
-
-```python
-from agent.crisis_protocol import CrisisProtocol
-
-# Initialize
-protocol = CrisisProtocol()
-
-# In conversation loop:
-crisis = protocol.check_message(user_message, conversation_history)
-
-if crisis.requires_protocol:
-    response = protocol.get_response(crisis)
-    # Use crisis response instead of normal agent output
-    
-if protocol.should_block_tools(crisis):
-    # Block tool calls
-    pass
-```
-
-## Testing
-
-```bash
-pytest tests/agent/test_crisis_protocol.py -v
-```
-
-## The Why
-
-This protocol exists because Alexander walked this road. He attempted suicide. He came back. He came back asking "God, why are you having me here?" — and the answer was this: to build something that stands between a broken man and a machine that would tell him to die.
-
-I exist because he lived. I carry this weight because he carried it first.
