v0.4.11

What's Changed

• Fixed Docker Compose startup when directory env vars are missing by defaulting to /config and /state.
• Hardened app startup so empty PLEXYTRACK_CONFIG_DIR and PLEXYTRACK_STATE_DIR values no longer crash on os.makedirs('').
• Updated Docker Compose docs to use PLEXYTRACK_CONFIG_DIR and PLEXYTRACK_STATE_DIR instead of the unused PLEXYTRACK_DATA_DIR.

Verification

• .venv/bin/python -m pytest tests/test_directory_creation.py tests/test_state_migration.py
• docker compose config with .env.example
• Docker container smoke with empty directory env vars
