Add tool filtering functionality that intercepts MCP tools/list and tools/call requests using Cedar policies; unauthorized tool calls return HTTP 200 with JSON-RPC "Invalid params" error (-32602); includes template-based policy generation, response filtering, and extensive test coverage for both allowed and denied scenarios. An additional option `--tools` is available for the `thv run` command.
