Add discovery-helper tests (env var override, PATH fallback, missing binary) and command tests that point M2PACK_BINARY at a Python stub script echoing canned JSON per subcommand. Cover success paths, non-zero exit, non-JSON output, JSON-array output, and missing binary. Extend the MCP schema mirror test to cover all 12 tools and add dispatch tests for the new m2pack_* argv translation.
