Adds an MCP host layer so external MCP servers (AST/LSP code-intelligence, package resolvers, etc.) can be mounted at startup and surface their tools/list as first-class Correx tools named mcp__<server>__<tool>. Each MCP tool is a Tool+ToolExecutor, so it rides the normal ToolExecutor path and inherits tier gating, receipts, and event-recorded execution (#5) with zero special-casing; replay reads the recorded receipt rather than re-calling the server (#8/#9). - McpProtocol/McpStdioClient/McpTool/McpMounter in infrastructure:tools (stdio JSON-RPC 2.0, tools/* slice only). Capabilities empty; safety via default T2 tier since external side effects are opaque. - [[mcp]] config (id/command/env/tier) + array-of-tables parsing. - Main wires mounted servers into extraTools (main + per-workspace paths) with a shutdown hook; a server that fails to start is logged and skipped. - Tests: in-process fake transport (handshake/list/call/error + tool mapping), [[mcp]] parser.
