Fnos packaging (#2524)
* feat(packaging): add fnOS FPK packaging and CI workflow Add packaging/fnos/ shell (manifest, lifecycle cmd scripts, install/ upgrade/uninstall wizards, desktop entry, EULA) plus in-repo build script. A release now auto-builds langbot-<tag>-fnos.fpk via .github/workflows/build-fnos-fpk.yaml, uploaded to the release assets. * ci(fnos): skip release upload on manual dispatch github.event.release.tag_name is empty when triggered via workflow_dispatch, causing 'gh release upload' to fail with 'requires at least 2 arg(s)'. Restrict the step to release events. * ci(fnos): normalize release asset name Strip a trailing -fnos from the tag-derived version before appending the suffix, avoiding langbot-<v>-fnos-fnos.fpk when the tag itself already carries -fnos. * ci(fnos): use release tag version for auto build, manifest for manual Auto build (release/tag) reads version from tag like other release workflows; build.sh strips the v prefix when injecting into manifest. Manual dispatch falls back to the version maintained in manifest. * feat(fnos): add post-install deployment notice to install wizard Last wizard step now informs users that first startup takes about 5-10 minutes for dependency setup before the web UI is ready. * docs(fnos): add packaging directory README * refactor(fnos): rename app from ai.langbot to langbot Rename appname, desktop entry, data share, build artifacts, and all references from ai.langbot to langbot across packaging files. --------- Co-authored-by: dadachann <185672915+dadachann@users.noreply.github.com>
