Match those portable features and the worker policy defaults. Keep architecture-specific drivers and tracing implementations separate. Record the audit and add a check of 90 required features against generated Kconfig output.

Validation: the generated ARM configuration failed the requirements before the changes and passes all 90 after resolution. XFS from the booted ARM image is retained. The previous incomplete build was stopped. This replacement build is for the isolated, cordoned ARM canary; do not start a fleet roll.

The ARM canary exposed missing WireGuard. The feature audit also found that ARM trunk lacked the XFS support in the booted ARM image, PSI and delay accounting, persistent crash records, and security and watchdog features present on the working AMD64 workers.
