/**
 * MCP (Model Context Protocol) server for the codebase semantic search.
 *
 * Exposes four tools to any MCP-compatible client (Claude Code, GitHub
 * Copilot Chat, OpenCode, Codex, etc.):
 *
 *   - codebase_semantic_search — query the index by meaning
 *   - codebase_read_file      — fetch a file slice by line range (sed -n 'A,Bp')
 *   - codebase_clip           — fetch a clip by short numeric id (from search)
 *   - codebase_stats          — chunk count and collection name
 *
 * Transport: stdio. The agent runtime spawns this process on demand and
 * exchanges JSON-RPC over stdin/stdout. No port, no daemon.
 *
 * The clip store is per-process and ephemeral — each MCP server start
 * starts with an empty store. Callers who need an id must run a search in
 * the same process to receive it.
