Refactor: Remove tools module and related functionality

- Deleted the tools module which included ModelDiscovery, HealthMonitor, CostCalculator, and ProviderRateLimiter.
- Updated lib.rs to remove references to the deleted tools module and restructured the module exports.
- Removed the sdk.rs file, consolidating SDK-related functionality into core and other relevant modules.
- Adjusted documentation to reflect the changes in features and structure of the SDK.
