Full changelog

Resource Reading Broken: Fixed critical bug where resources could be listed but not read
- Issue: Resources were registered by method name but looked up by URI, causing "Resource not found" errors
- Root Cause: #[server] macro registered resources using resource_name instead of resource_uri_template as the DashMap key
- Impact: All resources/read requests failed with -32004 error even for valid resources
- Fix: Changed registration in turbomcp-macros/src/server.rs:436 to use URI as key
- Location: crates/turbomcp-macros/src/server.rs:436
- Example: #[resource("stdio://help")] now registers with key "stdio://help" not "help"
- Breaking Change: No - this was a bug preventing correct MCP behavior
- Regression Test: Added test_resource_registration_lookup_by_uri to prevent future regressions
- Reported By: turbomcpstudio dogfood team via RESOURCE_READ_ISSUE.md
- Severity: Critical - Completely broke resource reading functionality
