rust-search-integration — Hybrid code search for a Rust codebase

Purpose: Give a Rust project a fast, hybrid (lexical + semantic) search surface that returns ranked, source-anchored hits in milliseconds — usable both as a library call inside the crate and as a robot-friendly CLI for agents.

YOU MUST PRODUCE A REAL INTEGRATION, NOT A DESCRIPTION. Write SEARCH-INTEGRATION-PLAN.md, then land an in-tree search module and wire it to a query surface.
