Closes#48274
Previously, the Copilot language server would continue running even when
`disable_ai: true` was set in settings. This change ensures Copilot
properly responds to the `disable_ai` setting:
- Add `disable_ai` check in `start_copilot()` to prevent starting when
AI is disabled
- Modify the `SettingsStore` observer to shut down the running language
server when `disable_ai` changes from false to true
- Add tests for all scenarios:
- Copilot doesn't start when `disable_ai` is true
- Copilot stops when `disable_ai` becomes true
- Copilot can start again when `disable_ai` becomes false
Release Notes:
- Fixed Copilot starting when disabled_ai: true
