fix(PendingRequestMap): resolve type name conflict between env.ts interface and call.ts class

- Remove PendingRequestMap interface from env.ts (had reduced signature missing deadline, identity typed as unknown)
- Add CallMap interface in env.ts with full call() signature matching the class
- Update EnvOptions.callMap to use CallMap type
- Export PendingRequestMap class directly (remove PendingRequestMapClass alias)
- Export CallMap type from index.ts instead of old PendingRequestMap interface
