fix(stream): Enable WebSocket/SSE/HTTP by default

Changed default_value to default_value_t for boolean flags.

Before: --websocket flag required, defaults to false
After: WebSocket/SSE/HTTP enabled by default

This fixes the issue where users had to explicitly add --websocket
to get the WebSocket endpoint working. Now the stream command works
out of the box with all transport methods enabled.

Usage:
  osvm stream --programs pumpfun --port 8080  # All enabled
  osvm stream --no-websocket                  # Disable WS
  osvm stream --no-sse --no-http              # Only WS
