* feat(server): add Schema validation system and binary encoding optimization

## Schema Validation System
- Add lightweight schema validation system (s.object, s.string, s.number, etc.)
- Support auto type inference with Infer<> generic
- Integrate schema validation into API/message handlers
- Add defineApiWithSchema and defineMsgWithSchema helpers

## Binary Encoding Optimization
- Add native WebSocket binary frame support via sendBinary()
- Add PacketType.Binary for efficient binary data transmission
- Optimize ECSRoom.broadcastBinary() to use native binary

## Architecture Improvements
- Extract BaseValidator to separate file to eliminate code duplication
- Add ECSRoom export to main index.ts for better discoverability
- Add Core.worldManager initialization check in ECSRoom constructor
- Remove deprecated validate field from ApiDefinition (use schema instead)

## Documentation
- Add Schema validation documentation in Chinese and English

* fix(rpc): resolve ESLint warnings with proper types

- Replace `any` with proper WebSocket type in connection.ts
- Add IncomingMessage type for request handling in index.ts
- Use Record<string, Handler> pattern instead of `any` casting
- Replace `any` with `unknown` in ProtocolDef and type inference
