Describe the bug

Terminates silently when there is a syntax error in config.json.
As a result, the user cannot determine what went wrong.

Affected version

Steps to reproduce the behavior

1. Edit ~/.copilot/config.json to intentionally introduce a syntax error (e.g., remove a comma).
2. Run copilot in the terminal.
   3.It exits immediately without any error message.

Expected behavior

Expected behavior: either report the syntax error explicitly, or ignore the invalid config and continue to start.
