Gate desktop auto-updates with AppBuildInfo.enableAutoUpdate.
Stealth artifacts disable desktop update initialization, manual checks, and appcast resolution. However, unavailable feature flags default autoUpdateEnabled to true, so desktop startup can still contact the appcast service.
Apply the compile-time gate only to macOS and Windows paths. Leave Android sideload updates outside this gate.

🔵 Needs a closer look
It rewires startup, native updater callbacks, retries, lifecycle recovery, and dependency injection across multiple layers, warranting final human validation.
Pull request overview
Decouples desktop update checks from core startup and adds bounded feature-flag reads, retries, and recovery triggers.
Changes:
- Starts desktop checks independently after five seconds.
- Adds retry/backoff handling and lifecycle/VPN recovery.
- Identifies update-service verification requests with a custom User-Agent.

Desktop update checks already ran at startup, but could be held up by core initialization or feature-flag requests. Start them independently so clients can check for updates even when the core is unavailable.
This addresses the startup and recovery portion of getlantern/engineering#3903
