The manifest gains `assets` (linux-x64 / windows-x64 → archive URL);
top-level `url` stays the Linux tarball for 0.2.1 installs. A Windows-
only test applies a bsdtar zip over a running exe (PING.EXE copy) and
checks it is parked as .old and swept next start; Linux-layout tests
(exec bits, symlinks) skip on Windows.

Updater: watch-together --upgrade checks updates/manifest.json,
downloads the tarball, verifies sha256, applies over the live
install (extract-temp + delete-first move-over; rename-safe on
Linux while running). Zero Flutter imports, 7 tests incl.
stub-server flows. Version stamped via --dart-define=APP_VERSION
in package script. Warns (never silently jumps) on proto mismatch.
Roadmap: phases retired as tracker (history in git log), now flat
Built/Backlog/Epics/Deferred; Jellyfin next feature, transcode
never; updater expansion stays an epic. Endpoint publishing
(manifest + release tarball) is user-owned.
