"""Tests for the shell scripts (close_issue.sh, mark_issue.sh).

These are integration-style tests that verify the scripts':
  - argument validation and error messages
  - exit codes on bad input
  - correct curl command construction (via a mock curl wrapper)

We do NOT make real API calls. Instead, the tests verify that the scripts
fail-fast with proper error messages when given no arguments.
