fix: add missing agent-context extension entries to Cline _expected_files

TestClineIntegration._expected_files() overrides the base-class version but
was not updated when the bundled agent-context extension files were added to
test_integration_base_markdown.py, causing test_complete_file_inventory_sh
and test_complete_file_inventory_ps to fail.

Fixes #2796
