p2.6: partition dcache by caller class; pin restricted workspace
Digest, chunk-embed, and question-embed keys include fleet|restricted so a fleet caller cannot observe a restricted cache hit. Digest.Run takes the class from permit_restricted. A permit_restricted caller whose keys.toml workspace is not guardian-star is refused at Search (no Honcho request) and flagged at serve start and keys reload. docs: P3 restricted callers search like the fleet; cache/logs isolate.
