Pull request overview

Adds support for selecting the Mergify YAML config via CLI/environment for CI scope detection, with a regression test around MERGIFY_CONFIG_PATH behavior.

Changes:

• Adds MERGIFY_CONFIG_PATH as an envvar source for the ci scopes --config option and tightens path validation.
• Adds a test asserting that an empty MERGIFY_CONFIG_PATH should fall back to config auto-detection.
