🐛 Fix test scripts: Node 26 doesn't auto-discover tests in directory args

node --test src/ on Node 26+ treats src/ as a module path, not as a
directory to scan for test files, producing a 'Cannot find module'
error. Switch the test scripts to an explicit glob that lists all
*.test.ts files under src/.

Affects test, test:ci, test:unit.
