fix(desktop): strip AppImage ARGV0 before child shells (#2588)

Browse Source 
AppImage exports ARGV0 into the process environment. zsh treats that as
argv[0] for every external command, which broke Python venv detection in
the integrated terminal and managed OpenCode sessions.

Clear ARGV0 in Electron before login-shell probing, refuse to re-apply it
from shell snapshots, and strip it from terminal PTY and managed OpenCode
launch environments.

Running a packaged Linux AppImage requires FUSE (`libfuse.so.2`, typically `libfuse2` / `libfuse2t64` on Debian/Ubuntu). Without FUSE, start with `APPIMAGE_EXTRACT_AND_RUN=1`. Keep the AppImage on a writable path so in-app updates can replace it.
Desktop clears AppImage `ARGV0` from `process.env` before probing the login shell and starting the in-process server. Leaving it set makes zsh rewrite argv[0] for integrated-terminal and managed-OpenCode child commands to the AppImage path.
Linux updates are supported only when the packaged app is running from a writable AppImage. Update checks, downloads, and installation report an actionable error when `APPIMAGE` is missing, invalid, or read-only; a missing release feed (`latest-linux.yml` 404 before the first Linux publish) is treated as “no update available”. macOS and Windows updater behavior is unchanged. Release builds keep `latest-linux.yml` (x64) and `latest-linux-arm64.yml` separate and validate each manifest against its AppImage before upload. Linux AppImages download full updates (no `.blockmap` differential channel yet).
