# T-687: Fix audit YAML writer — escape quotes in findings to prevent parse errors

## Context

Audit YAML output had broken strings — embedded double quotes in mitigation text caused YAML parse errors (e.g., `fw fix-learned T-XXX "description"` inside a YAML quoted string). Fixed the source string and hardened the YAML writer to properly escape backslashes and quotes. Also fixed the existing broken file (2026-03-09.yaml). Related: R-018 (invalid YAML data disappears without error).

## Acceptance Criteria

### Agent
- [x] Fixed broken YAML in `.context/audits/2026-03-09.yaml` (unescaped quotes)
- [x] Changed `warn()` argument to use single quotes instead of embedded double quotes
- [x] Hardened YAML writer to escape backslashes then double quotes in finding strings
- [x] All existing audit YAML files parse without errors

## Verification

# All audit YAML files parse correctly
python3 -c "import yaml, glob; [yaml.safe_load(open(f)) for f in glob.glob('.context/audits/2026-*.yaml')]"
# Writer has proper escaping
grep -q 'escape backslashes first' agents/audit/audit.sh
