textproc/tgrep: Add port: Trigram-indexed grep for fast regex search in large codebases locally
Trigram-indexed grep with a client/server architecture for fast regex
search in large codebases.
Tools like grep and ripgrep scan every file on every search - O(total
bytes) per query. In a 100k+ file monorepo, that's painfully
slow. tgrep pre-builds a trigram index so searches only touch the
small set of files that could match.
