Launcher core that reuses services/update_service: seed default config into
~/.cmbot on first run, check the manifest, download the release zip, verify
SHA-256, extract, validate version, swap into app/ (keeping app.old/ for
rollback), then launch app/CMBot.exe. Degrades to the local version on any
failure; checks install-root writability before updating.
- update_service: UpdateInfo gains sha256/size/min_supported; release URL
resolved to absolute; extract make_auth_header + add download() helper
- tests/test_launcher.py: 11 tests (seed, find-root, swap, sha mismatch,
no-update); also verified end-to-end against a local HTTP server
