This release makes MCP Failure Lab available as an npm CLI and adds JSON-driven scenario execution and structured reporting.

You can now run deterministic failure scenarios directly from the command line, inspect results in console or JSON format, and use exit codes for CI workflows. The release also includes a reproducible terminal demo and fixes the packaged CLI executable so the tool works correctly through npx.

MCP Failure Lab is now published to npm:

npx mcp-failure-lab --help

Users of npm version 0.3.0 should upgrade to 0.3.1 or later because 0.3.0 contains a broken CLI executable.
