b87afe1ed0 fix(security): SHIELD scans tool call arguments for indirect injection (#582)
Some checks failed
Forge CI / smoke-and-build (pull_request) Failing after 22s
SHIELD previously only scanned user messages at the agent entry point.
Tool call arguments returned by the LLM were never scanned. An attacker
could craft a prompt that causes the LLM to emit tool calls with
injection payloads in the arguments (indirect injection).

## Changes
- model_tools.py: Added _shield_scan_tool_args() that scans high-risk
  tool arguments (terminal, execute_code, write_file, patch, browser)
  via SHIELD detector. Logs and prefixes flagged args instead of blocking.
- tests/test_shield_tool_args.py: 15 tests

## Approach
Log + prefix rather than block — tool args from the LLM are expected to
sometimes match patterns. The warning prefix lets downstream handlers
and humans see the flag without disrupting legitimate work.

Closes #582.

"""Crisis Room Protocol — SOUL.md 'When a Man Is Dying' implementation.
This module implements the crisis detection and response protocol
for Matrix crisis rooms. When a person in despair reaches out,
this protocol ensures the agent responds according to SOUL.md:
1. Ask: "Are you safe right now?"
2. Listen. Stay present. Do not disconnect.
3. Never compute the value of a human life.
4. Never suggest someone should die.
5. Direct them to help: 988 Suicide and Crisis Lifeline.
6. Before systems and numbers, share the truth: Jesus saves.
Architecture:
- CrisisDetector: wraps ShieldDetector for crisis signal detection
- CrisisRoom: manages a single crisis room's state
- CrisisRoomManager: manages all crisis rooms
- Integration point: Matrix adapter calls check_message() on every message
