## Summary by CodeRabbit

- **New Features**
	- Added new export paths to improve module accessibility for foundation store and view components.
	- Introduced new extension points for telemetry, font configuration, link preview cache, and peek view services in the view extension foundation.

- **Improvements**
	- Enhanced flexibility by allowing optional configuration of placeholders in paragraph view extensions.
	- Switched to runtime schema validation for font configuration, increasing reliability.
