Default plugins disabled; skip loading disabled

Change plugin loader to treat plugins as disabled by default (unless the id/dir is 'napcat-plugin-builtin') by using nullish coalescing when reading statusConfig. Add an early-return guard in the plugin manager/adapter that logs and skips loading when entry.enable is false. This prevents disabled plugins from being loaded automatically and provides a clear log message when skipped.
