Lets users choose among the last 3 releases (v3.6.3 latest, v3.6.2,
v3.6.1) instead of only ever flashing the newest build - handy for
testing or rolling back. Archives the real historical binaries for
v3.6.1/v3.6.2 under versions/, each with its own manifest.json.
Documents the archival step as part of the standard release workflow
in CLAUDE.md so the picker stays current on future releases.
