Subject: [PATCH] fix: set WorkingDirectory in systemd service for control UI
 assets

The systemd service file was generated without a WorkingDirectory directive,
causing the control UI to fail with "Control UI assets not found" because
the gateway process ran with cwd set to the user's home directory instead
of the repo/package root.

The resolveControlUiRoot() function uses process.cwd() as a fallback for
finding dist/control-ui, which failed when cwd was wrong.

This fix derives workingDirectory from the CLI entrypoint path for all
production runtime paths (node, bun, auto) so that `moltbot gateway install`
and `moltbot doctor --repair` generate service files with the correct
WorkingDirectory.
