Per decision: displays need none of the fleet-wide common scope's software, so
the gea-shopfloor-display scope carries everything it enforces and does not
inherit common. This avoids repackaging common's SMB-backed payloads for a
share-less display.
- Invert the client common-merge switch: -NoCommon (default-on) becomes
-IncludeCommon (default OFF). A scope now enforces alone unless opted in.
The capability stays for a future share-less non-display PC; displays omit it.
- Drop the common SMB-payload audit + inheritance sections from the display
seed comments and docs (GE-ENFORCE-DISPLAY.md); document self-sufficiency.
- GE-ENFORCE-CLIENT.md: common-scope inheritance is now opt-in.
