Full changelog

Resource Listing Metadata Loss: Fixed critical bug where Client::list_resources() was discarding resource metadata
- Issue: Method was returning only URIs (Vec<String>), throwing away all metadata from server
- Impact: Broke applications like turbomcpstudio that needed resource names, descriptions, MIME types
- Root Cause: Implementation was mapping ListResourcesResult::resources to just URIs instead of returning full Resource objects
- Fix: Changed return type from Vec<String> to Vec<Resource> per MCP 2025-06-18 spec
- Breaking Change: No - Resource type was already exported and clients can access .uri field
- Files Changed:
  - turbomcp-client/src/client/operations/resources.rs - Core fix to return full Resource objects
  - turbomcp-cli/src/executor.rs - Updated to handle Resource objects
  - turbomcp-client/src/lib.rs - Updated documentation examples
  - turbomcp/examples/comprehensive.rs - Enhanced to display resource metadata
  - turbomcp/examples/unix_client.rs - Updated to use resource.uri field
- Reported By: turbomcpstudio team
- Severity: High - Breaks core resource functionality
