v0.3.11

### Added
- **Async preset loading** — presets with media/video layers decode in a background thread, keeping current content playing; atomic swap on completion with pulsing status bar indicator and preset button highlight
- Generation-based cancellation for rapid MIDI preset cycling (only final preset applies)

### Fixed
- **Webcam layer preset ordering** — loading a preset with a webcam layer no longer appends it to the end of the stack; webcam content is now placed in-place at its correct index, preventing extra stray layers and layer count growth on repeated save/load cycles
- **Webcam decode panic hardening** — backoff (50ms sleep) after corrupted frame decode panics to avoid hammering a broken camera; auto-stop capture thread after 10 consecutive panics with user-visible error log
- Log GPU present mode and available modes on startup for easier driver issue diagnosis
- **Clippy `never_loop` lint** — replace `while`+`break` with `match` drain-and-retry in preset loader, unblocking CI for v0.3.11 release
