A new gate, tengu_quiet_lantern, controls whether the server classifier falls back to local when unsupported

What

A new feature flag, tengu_quiet_lantern, has been added to control whether auto mode's server-side ("arbiter") classifier falls back to local classification specifically when the server returns no result or reports the feature as unsupported.

Why

This lets the server-classifier fallback behavior be turned on or off independently for different accounts, rather than being hard-coded into every install. Nothing has been read yet about which accounts have it on.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
