refactor(Bun > npm + Jest): Jest runs E2E via Babel (uniform TS/ESM), minimal module mapping, dotenvx for envs

- Switched Bun TS runner to Node + tsx with dotenvx wrapping for env loading.
- Replaced Bun E2E runner with Jest using a dedicated jest e2e config
- Resolved CJS/ESM breakages by using Babel transfomer for .ts|.js| in Jest.
- Avoided duplicated module resolution: ignored `.nx/` and `dist/` in Jest.
- Prevented hijacking external `@lit-protocol/*` and only map local packages
