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.

;; search public API — assembles the canonical Haskell source from all layers.
;; Tests and callers concatenate `search/src` with their own top-level bindings
;; (e.g. "result = lookupTerm \"cat\" idx\n") and evaluate via the haskell-on-sx
;; interpreter. Public Haskell entry points: indexDoc, lookupTerm, deleteDoc,
;; docFreq, allTerms, tokens, positioned, evalQuery, parseQuery, searchQuery,
;; rankTfIdf, rankBm25, topNTfIdf, topNBm25, fedIndex, aclFilter, searchTfIdfAcl,
;; topNTfIdfAcl, searchBm25Acl.
