How to use CSOURCE: tie answers to their source and cascade-purge

CSOURCE links cache entries to the source they derived from, so when the source changes you can purge everything built on it in one move.

Cached answers derive from sources — a doc, a config, an API. CSOURCE wires that link, so freshness is something you can prove, not hope for.

> CSOURCE LINK pricing-doc-v3 "what does the Pro plan cost?" TENANT acme
OK
> CSOURCE LIST pricing-doc-v3
1) "what does the Pro plan cost?"
2) "is Pro cheaper annually?"
> CSOURCE PURGE pricing-doc-v3
"purged 2 entries derived from pricing-doc-v3"

When the pricing doc revs, purge by source — no hunting for affected entries.
