'No copilot-instructions.md found' notice is misleading when global config exists

[rstallworthbf]

Describe the bug

When opening the Copilot CLI outside of a git repository, the notice No copilot-instructions.md found. Run /init to generate. is misleading. it implies no instructions file was found at all, even when a global ~/.copilot/copilot-instructions.md exists and is being used.

Affected version

GitHub Copilot CLI 1.0.49.

Steps to reproduce the behavior

1. Create a global instructions file at ~/.copilot/copilot-instructions.md
2. Open Copilot CLI from a directory that is not a git repository
3. Observe the notice: No copilot-instructions.md found. Run /init to generate.

Expected behavior

1. Create a global instructions file at ~/.copilot/copilot-instructions.md
2. Open Copilot CLI from a directory that is not a git repository
3. Observe the notice: No repository-level copilot-instructions.md found. Run /init to generate.
