Pi-Kit API entrypoint

Thin wrapper that defers to the modular `pikit_api` package. The behavior and
CLI flags remain compatible with the previous single-file script:

--apply-update      Apply latest release (non-HTTP mode)
--check-update      Check for latest release (non-HTTP mode)
--rollback-update   Roll back to last backup (non-HTTP mode)
