Sky Master Frigate Fix

Requires 6TP - Type 36 Frigate and its original dependencies. Redirects its Game Master placement registry to an independent cleaned ship variant. Removes missing crane and coffee-machine child references and the cinematic child. Uses a single hull placement preview. Keeps the remaining ship structure and interior references. No model or texture binaries included. Local PC resource loading, catalog redirection and spawn tests passed. PS5 crash resolution and multiplayer placement are not yet verified. Existing placed ships are not migrated.
