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

## Description
There is a naming conflict documented in call-protocol.md § Bugs:
- `src/env.ts` exports a `PendingRequestMap` **interface** (reduced signature: missing `deadline`, `identity` typed as `unknown`)
- `src/call.ts` exports the `PendingRequestMap` **class** (full signature with all options)
- `src/index.ts` re-exports the interface as `PendingRequestMap` and the class as `PendingRequestMapClass`
The documented `PendingRequestMap` in the architecture refers to the **class**, but importing the type gives the reduced interface. This creates confusion for consumers.
The fix should:
1. Remove the `PendingRequestMap` interface from `env.ts` entirely
2. Rename the class export in `index.ts` from `PendingRequestMapClass` to just `PendingRequestMap` (both the class and type export)
3. Update the `EnvOptions.callMap` type to reference the actual class or a proper minimal interface
This is independent of ADR-005/006 and can be fixed immediately. Note: ADR-005 will later change the `call()` return type from `Promise<unknown>` to `Promise<ResponseEnvelope>`, but fixing the naming conflict now is clean and doesn't block on that.
## Acceptance Criteria
- [x] `PendingRequestMap` interface removed from `env.ts`
- [x] `index.ts` exports the class as `PendingRequestMap` (no `PendingRequestMapClass` alias)
- [x] `EnvOptions.callMap` type uses the actual `PendingRequestMap` class type or a proper minimal interface
- [x] Existing tests pass
- [x] No consumer-visible breaking change (the class has all methods the interface had, plus more)
## References

- src/index.ts:6,14 (re-exports)
- src/call.ts:68 (class definition)
## Notes
Renamed the interface to `CallMap` instead of completely removing it, since `EnvOptions.callMap` needs a type for dependency injection (not every consumer needs the full `PendingRequestMap` class — they may provide a minimal call-map-like object). The `CallMap` interface now matches the full `call()` signature of the class (including `deadline` and properly typed `identity`).
## Summary
Resolved the PendingRequestMap type name conflict. Changes:
- Removed `PendingRequestMap` interface from `env.ts` and replaced it with `CallMap` interface that matches the full `call()` signature (including `deadline` and properly typed `Identity` parameters)
- Updated `EnvOptions.callMap` to use `CallMap` type
- Updated `index.ts` to export `CallMap` type from `env.js` (instead of `PendingRequestMap`) and export the `PendingRequestMap` class directly (instead of as `PendingRequestMapClass`)
- Build, lint, and all 75 tests pass
