chore(test): add terraform tests for jetbrains, zed, code-server and keep mixed mode

- Add .tftest.hcl for jetbrains, zed, and code-server
- Remove Bun tests for these migrated modules only
- Keep Bun tests for other modules during transition
- Update contributing guide to mention terraform test
- Include runner script to execute terraform tests across modules
