Add Python packaging and automated release workflow to enable
versioned releases of the BLE interface.
Changes:
- Add pyproject.toml with package metadata and dependencies
- Add GitHub Actions release workflow with validation and artifact generation
- Add CHANGELOG.md documenting v0.1.0 installation system features
The release workflow validates version consistency, runs tests,
generates release artifacts (installer, config, source tarball),
and creates GitHub releases automatically from git tags.
