<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
Closes [MPT-16657](https://softwareone.atlassian.net/browse/MPT-16657)

### Release Notes

- Simplified .coderabbit.yaml by replacing extensive local settings with
a remote configuration reference
- Removed local configuration sections (language, tone, reviews, tools,
path instructions, feature toggles)
- Added top-level remote_config with field `url` to point to an external
.coderabbit.yaml for centralized configuration management
