Restore upstream LICENSE files for every vendored grammar and C library across both vendored trees (19 grammar dirs, lz4, zstd, simplecpp, verstable, wyhash, ts_runtime, common, mongoose, xxhash, yyjson; SQLite public-domain notice). Add the nomic-embed-code Apache-2.0 license plus a NOTICE describing the embedding derivation. First-party grammars carry the project MIT license. THIRD_PARTY.md now defers grammar provenance to the verified MANIFEST.md instead of a stale hand-written table (which misattributed clojure as EPL-1.0 — it is CC0-1.0), covers all vendored libraries, and documents the Hybrid LSP reference servers and stdlib type-data provenance (typeshed, Go stdlib introspection, hand-curated specs).
