install.sh asked /releases/latest and installed whatever came back. That is v0.1.0 today, which predates the updater, and it was about to get worse: the `stable` pointer release write-manifest.sh creates is non-prerelease and holds only latest.json, so from the next v* tag onward it would have WON /releases/latest and the installer would have found nothing to install. So resolve a channel instead of a "latest". `--channel stable|dev` (or TS_CHANNEL), default stable, named to match update.rs's Channel exactly. dev reads /releases/tags/dev. stable reads the pointer's own latest.json, takes its version, and installs that v* release — the same file the app reads, so the installer and the updater cannot disagree about what stable means. Two things found on the way. The dev release's description still told people to run the stable command, and always would have: publish-release.sh writes a body only when it CREATES a release, and a fixed-tag release is only created once, so the text froze at the first build. The 409 path now PATCHes it. And the asset greps were unanchored, so a .AppImage.sig URL could match as the bundle URL — harmless by coincidence, not by construction.
