"""Integration tests for adapter setup tuple unpacking (1M-182).

Tests to prevent regression of tuple unpacking bugs in init_command.py
where default_values from adapter configuration were being discarded.

Covers:
- GitHub programmatic setup (non-interactive)
- Jira programmatic setup (non-interactive)
- Interactive setup for GitHub and Jira
- Verification that default_values are properly merged into config
