agentmd: run CLI via tsx in subprocess tests

The release workflow runs `npm test` before `npm run build`, so the new
cli.test.ts's dependency on `dist/cli.js` broke the v0.2.0 publish. Invoke
the CLI straight from source with `node --import tsx src/cli.ts` instead
— matches how the test runner itself loads TypeScript and removes the
ordering dependency.
