Tests for SOUL.md support in the memory API (GET /api/memory, POST /api/memory/write).

SOUL.md lives at HERMES_HOME/SOUL.md (not in the memories/ subdirectory).
This test file verifies:
- GET /api/memory returns soul content, path, and mtime
- POST /api/memory/write with section="soul" writes to HERMES_HOME/SOUL.md
- Redaction still applies to soul content
- Existing memory/user sections remain unaffected
