CI release pipeline in .gitea, wishlist into backlog

release.yml (tag v* or manual dispatch): beta Flutter per local
convention, Linux build deps, package script tarball, artifact
upload, then release_publish.sh creates the Forgejo release,
uploads the asset, and commits updates/manifest.json back to
main. Workflows moved .github -> .gitea to match the forge setup.
Wishlist.md consumed into roadmap backlog: EOF stall + tiny buffer
bugs prioritized, recovery controls, link conveniences, time UI,
shortcuts, shaders, avatar serving.
