Omit unbound forwarding-region callbacks only for exclusive Companion source roles. Reuse the compact neighbor sorter in repeaters for every RPC order and the CLI list, removing duplicate sort implementations while preserving storage and size gates.

"""Derive feature-preserving role definitions from effective application sources.

Shared compiler definitions cover application and helper translation units.

Unknown/custom roles keep the complete layout; room and sensor session fields

are never removed from builds that use them. Companions omit only unbound

forwarding-region callbacks because that role has no RegionMap.
