* feat: add resource parameter validation tests (RFC 8707)
Adds conformance tests for OAuth Resource Indicators (RFC 8707) implementation:
1. Resource parameter checks added to token-endpoint-auth-basic scenario:
- resource-parameter-in-authorization: Verify resource in auth request
- resource-parameter-in-token: Verify resource in token request
- resource-parameter-valid-uri: Verify valid canonical URI
- resource-parameter-consistency: Verify consistency between requests
2. New auth/resource-mismatch scenario:
- Tests that client rejects when PRM resource doesn't match server URL
- Server returns mismatched resource in PRM
- Test passes if client does NOT proceed with authorization
Also adds spec references for RFC 8707 and MCP resource parameter spec.
Closes#33
* fix: make resource consistency check a FAILURE and remove dead code
- Change resource parameter consistency from WARNING to FAILURE
- Remove unreachable protocol check in validateCanonicalUri
(URL constructor already validates scheme presence)
