Agent subprocesses (bash, python) previously inherited the container's default
working directory (/app), so files created with relative paths landed in the
ephemeral container layer and were silently destroyed on any docker compose up
--build or container recreation.
Set cwd=_AGENT_WORKDIR (resolved to <repo_root>/data at import time) and
HOME=_AGENT_WORKDIR on both subprocess launchers so that:
- pwd inside a bash tool returns the persistent data directory
- relative paths and ~ resolve to a location that survives rebuilds
- the agent can still cd to any absolute path it needs
The resolution uses pathlib.Path(__file__).parent.parent / "data", which
works for both Docker (/app/src → /app/data) and manual installs
(<repo>/src → <repo>/data) without requiring a new env var or compose change.
