FramePort finds new GitHub releases by itself and updates in one click: sidebar card + Library bar, a dialog with
the release notes, "Update and restart" (download, SHA256SUMS check, Windows signer check, swap script, relaunch),
optional automatic installs at the next start. CLI: --version, `frameport update [--check] [--yes]` and a
once-a-day hint. One version source (_version.py); releases also ship the CLI wheel and "What's new" from the
annotated tag; CI runs an update smoke test with each OS's archive.
