F-Droid Local Build Script

Runs the F-Droid build inside the fdroidserver Docker container.

USAGE:
    $0 [OPTIONS] [appid:versioncode]

OPTIONS:
    --no-cleanup    Don't remove container after build (useful for debugging)
    -h, --help      Show this help message

EXAMPLES:
    $0                                    # Build default (app.status.mobile:29500000)
    $0 app.status.mobile:29500000         # Build specific version
    $0 --no-cleanup app.status.mobile:29500000  # Keep container after build

ENVIRONMENT VARIABLES:
    FDROIDDATA_PATH    Path to fdroiddata repo (default: ./fdroiddata)

NOTE:
    The Status app build requires many hours due to Qt compilation.
    Make sure you have sufficient disk space (~100GB recommended).
