Module matcher 

Class matching — what a ClassRule claims.

Two types live here: RangeSet, the hand-rolled sorted/coalesced u64 range container the proxy uses instead of pulling in a dependency (nothing in the workspace offers one), and Matcher, the AND of the eight keys a rule may name.

The one rule that shapes everything below: an absent key never matches. A unit whose subgroup_id the wire did not carry does not match a subgroup_id matcher — it falls to the default class. None as wildcard was rejected outright, because it silently widens a rule aimed at video to also match audio.
