"""AI Local Stack Control v3.0 — Ankh of Jah

Direct launcher.  Run from the project root:

    python ai_lsc.py

No pip install, no entry-point scripts, no ~/.local pollution.
Reads .env (created by bootstrap.sh) for AI_LSC_BASE_DIR, then
points sys.path at src/ and calls main().

Works wherever it sits — fully portable.
