fix: critical streaming bugs for request and response streaming

[VikramAditya33]

Three critical bugs prevented HTTP streaming from working:

1. Request streaming - Missing super.resume() caused connections to abort after first chunk. Fixed by calling both uwsRes.resume() and super.resume() to properly resume both uWS and Node.js Readable. Fixes Critical Bug; Request Body Streaming Not Working #63

2. Binary content auto-parsing - Route registry eagerly parsed all content types including binary, preventing streaming. Fixed by skipping auto-parse for application/octet-stream and multipart. Fixes Route Registry Prevents Streaming for Binary Content #62

3. Duplicate Content-Length - Manually setting header before tryEnd() which also sets it. Fixed by letting tryEnd() handle it automatically. Fixes Duplicate Content-Length Header in Response Streaming #64

Changes:

• Fix resume()/pause() to handle both uWS and Node.js Readable
• Skip auto-parsing for streaming content types
• Remove manual Content-Length setting in stream()

Summary by CodeRabbit

• Bug Fixes
  • Improved handling of streaming media types (multipart/form-data, application/octet-stream) with automatic detection
  • Enhanced streaming request/response control with better automatic content-length management
  • Eliminated unnecessary body parsing for streaming content types
