When running plain `python script.py` or bare uvicorn, .env is never
loaded automatically. Added a dotenv bootstrap block at the top of
state.py that finds and loads the nearest .env file (walks up from
models/ to the project root). Uses load_dotenv with override=False so
explicitly set environment variables always win over .env values.
Gracefully skips if python-dotenv is not installed.
CFG.forge_dir, precon_dir, forge_decks_dir, forge_jar, and lab_jar
were only set via CLI args. When the server starts via uvicorn directly
(no CLI), all paths stayed empty and forge_card_loader could not find
the cardsfolder, causing 0 lands in every deck.
Fix: read FORGE_DIR, FORGE_JAR, PRECON_DIR, PRECON_DECKS_DIR,
FORGE_DECKS_DIR, and LAB_JAR from environment at import time, mirroring
the existing ANTHROPIC_API_KEY / XIMILAR_API_KEY pattern.
The precon deck list was missing after the monolith refactor because
PRECON_DIR was hardcoded in services/precon_service.py with no CLI arg,
env var, or auto-resolve fallback — unlike forge_jar, forge_dir, etc.
Changes:
- Add precon_dir field to Config class (models/state.py)
- Add --precon-dir CLI arg and PRECON_DIR env var support
- Add _resolve_precon_dir() with project-root, parent-dir, and
forge_dir-relative detection; creates dir as fallback for downloads
- Refactor precon_service.py to use _get_precon_dir() helper that reads
CFG.precon_dir at runtime instead of a hardcoded module-level Path
- Update routes/precon.py to use _get_precon_dir() for install endpoints
- Wire _on_startup to resolve precon_dir for uvicorn-direct launches
- Remove unused PRECON_DIR/PRECON_INDEX imports from routes/lab.py
- Audit confirms all other CFG path fields already have fallbacks
