giles 77ab827b91 search: Phase 4 federation merge + ACL post-filter + 21 tests ...

fedIndex merges per-peer inverted indices (union posting lists per term) after
relabelling local DocIds to global gid = peer*1000 + local — dedupe by
(peer,doc-id) is automatic and positions survive, so ranking runs once over the
merge and interleaves peers by score. ACL is a post-rank filter over an injected
permit predicate (searchTfIdfAcl/topNTfIdfAcl/searchBm25Acl). Roadmap complete,
122/122.
