fix(facts): fold visibility tier into hot-memory meta cache key

trustedFactReads is re-read from config on every stdio tool call, so the
reader's visibility tier can now flip within one server process. The
meta-hook cache key (source, session, allow-list hash) didn't capture it,
so a mid-session opt-out of facts.trust_local_reads could keep serving a
private-inclusive cached payload for the 30s TTL. Compute the visibility
filter before the cache lookup and append the tier to the key, restoring
the header's cross-tier no-bleed invariant.
