Testing skill (`contentstack-cli-tsgen`)

Commands

Command	What it does
`npm test`	Jest with `--testPathPattern=tests`; then `posttest` runs ESLint (package.json)
`npm run test:integration`	Jest only for `tests/integration`
`npm run prepack`	Build `lib/` (required before local `csdx plugins:link` style workflows)

tests/integration/tsgen.integration.test.ts spawns csdx tsgen with TOKEN_ALIAS.
Loads .env from package root via dotenv (path relative to test file). TOKEN_ALIAS must be defined or the suite throws at load time.
