Summary

• Adds @reforged/maker-appimage and registers it in forge.config.ts so Forge produces x64 + arm64 Linux AppImages alongside the existing macOS DMG/ZIP and Windows installer.
• Adds a publish-linux matrix job (ubuntu-latest + ubuntu-24.04-arm) to code-release.yml that installs the AppImage tooling (squashfs-tools, zsync, libfuse2t64) and runs electron-forge publish. finalize-release now depends on this job too.
• Adds a pnpm --filter code make:linux script that builds the AppImage from macOS via Docker (tar-streamed source, container-side node_modules) for local verification, since electron-forge can't natively cross-build AppImages from darwin.
• Drive-by: removes a duplicate const { isOnline } = useConnectivity() in SessionView.tsx left behind by a merge collision between fix(sessions): preserve prompt when sending while offline #1971 and fix(sessions): disable message send when offline #2121 — was failing typecheck on main.

Test plan

• Push a throwaway v0.0.0-linuxtest1 tag and verify publish-linux produces both x64 and arm64 AppImages in the draft GitHub release
• Confirm finalize-release waits for all three platform jobs before un-drafting
• Locally: pnpm --filter code make:linux produces an AppImage under apps/code/out/make/ (requires Docker Desktop ≥ 8 GB memory)
• Launch the produced AppImage on a Linux box and confirm the app boots
• Verify existing macOS DMG and Windows installer release flows still publish (no changes to those job definitions, but matrix needs was extended)

Notes

• Linux artifacts are unsigned (no gpg signing wired up); flag for follow-up if signed Linux builds are needed.
• libfuse2t64 is the Ubuntu 24.04 package name; if ubuntu-latest is bumped past 24.04 in the future, that line may need adjusting.

### Issue 1 of 2
.github/workflows/code-release.yml:218-222
**Unused matrix variable `arch`**

The `arch` field is declared in the matrix but is never referenced in any step — `electron-forge publish` detects the native architecture from the runner itself. Having a documented-but-unused variable is superfluous and could mislead future readers into thinking something explicit is being passed to the build command.

### Issue 2 of 2
.github/workflows/code-release.yml:219-222
The x64 runner uses `ubuntu-latest` while the arm64 runner pins `ubuntu-24.04-arm`. The `libfuse2t64` package name is Ubuntu 24.04-specific; if `ubuntu-latest` is ever resolved to a different LTS (22.04 uses `libfuse2`, and a future 26.04 may rename it again), this `apt-get install` step will fail. Using an explicit version for both runners makes the build reproducible and avoids the implicit coupling.

```suggestion
          - runner: ubuntu-24.04
            arch: x64
          - runner: ubuntu-24.04-arm
            arch: arm64
```

Pull request overview

Adds a Linux AppImage distribution path for the Electron “Code” app, integrating it into the existing Electron Forge packaging/publishing workflow and CI release pipeline.

Changes:

• Add @reforged/maker-appimage to Forge config so Linux AppImages are produced (x64 + arm64).
• Extend the GitHub Actions release workflow with a Linux publish matrix job and update release finalization dependencies.
• Add a local Docker-based make:linux script and ensure non-macOS window icons are explicitly set at runtime.
