…e tests - Fix transport schema enum to include both valid values (streamable-http, sse) instead of only the provided value, matching TypeScript SDK behavior - Fix doc.go examples to use bazaar.BAZAAR.Key() instead of bazaar.BAZAAR - Inline createMcpDiscoveryExtension into DeclareMcpDiscoveryExtension - Add negative validation tests for wrong type and empty toolName - Add edge case tests for whitespace-only toolName and invalid transport Co-Authored-By: Claude <noreply@anthropic.com>
