Fix macOS menu bar status-item storms during rapid gateway connection churn by removing stale SwiftUI-vended status items before adopting replacements and debouncing transient control-channel states.
Surface: macOS menu bar app, `MenuBarExtra` status item ownership, `ControlChannel` UI-observed connection state.

* macOS: honor Nix defaults suite; auto launch in Nix mode
Fixes repeated onboarding in Nix deployments by detecting nixMode from the stable defaults suite (ai.openclaw.mac) and bridging key settings into the current defaults domain.
Also enables LaunchAgent autostart by default in Nix mode (escape hatch: openclaw.nixAutoLaunchAtLogin=false).
* macOS: keep Nix mode fix focused
Drop the automatic launch-at-login behavior from the Nix defaults patch; keep this PR scoped to reliable nixMode detection + defaults bridging.
* macOS: simplify nixMode fix
Remove the defaults-bridging helper and rely on a single, stable defaults suite (ai.openclaw.mac) for nixMode detection when running as an app bundle. This keeps the fix focused on onboarding suppression and rename churn resilience.
