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>

+# LangBot fnOS Packaging
+
+This directory packages LangBot as a `.fpk` app for the fnOS App Store. It is a native deployment: no Docker involved — uv creates a Python virtual environment directly on the NAS, and Node.js v22 from the fnOS App Store provides the Box sandbox and npx MCP capabilities.

+Paths marked `[generated]` are produced by `build.sh`, ignored via `.gitignore`; everything else is a git-tracked source file.
+
+## Building
+
+### Locally
+
+```bash
+bash packaging/fnos/build.sh
+```
+
+Dependencies: python3 + Pillow, node + npm (or pnpm), fnpack (official fnOS packaging CLI, download from https://developer.fnnas.com/docs/cli/fnpack).
+
+The version comes from `version=` maintained in the manifest; it can also be injected: `FPK_VERSION=4.10.10-1 bash packaging/fnos/build.sh`.
+
+### CI
+
+[`.github/workflows/build-fnos-fpk.yaml`](../../.github/workflows/build-fnos-fpk.yaml) triggers automatically on Release publication and uploads `langbot-<version>-fnos.fpk` to the Release; it can also be triggered manually via workflow_dispatch.
+
+Version sources (consistent with the other release workflows):
+
+| Trigger | Version source |
+|---|---|
+| Release/tag auto build | Tag name (`v4.10.10-1` → in-package `4.10.10-1`; build.sh strips the `v` prefix on injection) |
+| Manual workflow_dispatch / local build | Version maintained in manifest |
+
+## Final Artifact
+
+`langbot.fpk` (gzip + tar archive), containing:
+
+- `manifest` — realigned and appended with a `checksum` field by fnpack
+- `app.tgz` — app payload (source, web/dist, uv binaries, entry configs)
+- `cmd/`, `config/`, `wizard/` — lifecycle scripts and wizards
+- `ICON.PNG`, `ICON_256.PNG`, `LICENSE`
+
+The first startup after installation takes about 5-10 minutes to finish dependency deployment (uv venv + sync); after that the web admin UI is reachable via the desktop icon or `http://<NAS-IP>:<port>` (default port 5300).
