fix: replace hardcoded bm_local_path with env var in justfile

The justfile had a user-specific path hardcoded for bm_local_path.
Now reads from BM_LOCAL_PATH env var (or .env via dotenv-load),
defaulting to empty which omits --bm-local-path entirely.
Also updates docs and README to use generic placeholder paths.
