- viz/capture.go: waveFormatExtensibleEx now flat struct (not embedded)
  Go pads waveFormatEx to 20 bytes (uint32 alignment), but the Windows
  C struct is 18 bytes — embedding caused SubFormat to land at wrong
  offset, breaking float32 detection (float=false bug)
- server.go: clamp position/length values > 24h to 0
  Winamp returns 0xFFFFFFFF for these fields when stopped/no track loaded
- .gitignore: exclude winamp/ dir and runtime .dat files
- config.yaml: added (gitignored) pointing to winamp/winamp.exe

Tested: Winamp 5.9 portable in winamp/, IPC connection verified,
viz loopback correctly detects 48kHz float32 stereo
