/**
 * msd-mcp-server — companion MCP server bin entry (ADR-1239 Phase C-2 / #1681).
 *
 * Lives at top-level bin/ (alongside install.js) — it is a PACKAGE bin the host
 * spawns via `npx msd-mcp-server` (or the global bin), NOT a per-runtime
 * artifact copied into a host's config dir. (Placing it under msd-core/bin/
 * would leak it into every runtime install + break golden parity.)
 *
 * A stdio JSON-RPC 2.0 server exposing MSD interface points 1 (command) + 5
 * (state IO) so any MCP-consuming host (Claude/Codex/OpenCode/VS Code/
 * Antigravity/Cursor) can drive MSD with no bespoke plugin. Delegates to the
 * tested server module (msd-core/bin/lib/mcp-server.cjs runServer). Reads
 * line-delimited JSON-RPC from stdin, writes one response + newline per
 * request, exits cleanly when stdin closes.
 *
 * The protocol logic (handleMessage) + the injectable-stream loop (runServer)
 * are unit-tested in tests/msd-mcp-server.test.cjs; the process lifecycle
 * (spawn → JSON-RPC → clean exit) in tests/msd-mcp-server-bin.test.cjs.
