Module Build

The packing script is tools/pack.py (Python standard library only, zero dependencies):

python tools/pack.py --check    # validate required files + script exec bits only
python tools/pack.py            # release build → dist/SvcHub_v<version>.zip
python tools/pack.py --tag dev  # test build → dist/SvcHub_v<version>_dev.zip

• The version is read from the version field of module.prop, producing dist/SvcHub_v<version>.zip; duplicate names are not overwritten — a _1/_2 suffix is appended
• New module files must be added to the REQUIRED_FILES list in tools/pack.py
• Each build overwrites dist/SHA256.txt (one line: hash + package name)
