trusty-search 0.3.19

//! Line-delimited JSON-RPC loop on stdin/stdout.
//!
//! Why: Claude Code launches MCP servers as subprocesses and communicates
//! over stdio with one JSON-RPC message per line. The shared
//! `trusty_mcp_core::run_stdio_loop` owns the parse/dispatch/write/flush
//! cycle so every trusty-* MCP server shares the same behaviour.
//!
//! What: [`run`] adapts an [`McpServer`] into the closure shape the shared
//! loop expects and delegates the loop body.
//!
//! Test: covered indirectly by `tools::tests` plus a smoke test in
//! `tests/stdio.rs` that pipes a `tools/list` request through the loop.
