* 🔗 fix: Normalize MCP OAuth `resource` parameter to match token exchange
The authorization request used the raw resource string from metadata while
the token exchange normalized it through `new URL().href`, causing a
trailing-slash mismatch that Cloudflare's auth server rejected. Canonicalize
the resource URL in both paths so they match.
* 🔧 test: Simplify LeaderElection integration tests for Redis
Refactored the integration tests for LeaderElection with Redis by reducing the number of instances from 100 to 1, streamlining the leadership election process. Updated assertions to verify leadership status and UUID after resignation, improving test clarity and performance. Adjusted timeout to 15 seconds for the single instance scenario.
* 🔧 test: Update LeaderElection test case description for clarity
Modified the description of the test case for leader resignation in the LeaderElection integration tests to better reflect the expected behavior, enhancing clarity and understanding of the test's purpose.
* refactor: `resource` parameter in MCP OAuth authorization URL
Updated the `MCPOAuthHandler` to ensure the `resource` parameter is added to the authorization URL even when an error occurs while retrieving it from metadata. This change improves the handling of invalid resource URLs by using the raw value as a fallback, enhancing the robustness of the authorization process.
* ✨ feat: Implement scanIterator method for Redis cluster client
This resolves the bug where `ServerConfigsCacheRedis#getAll` returns an empty object when a Redis Cluster (instead of a single node server is used)
* ✨ feat: Update cache integration tests for Redis cluster support
