Fix Xcode 27 beta warnings

pblazej · claude · pblazej · commit 98fc26e6abee · 2026-06-09T13:09:55.000+02:00
- Silence unstructured throwing Task warnings with try? / do-catch
- Replace deprecated onChange(of:perform:) via View+OnChange compat shim
- Use .task(id:) for visionOS immersive space lifecycle
- Wrap Slider-based RemoteAudioVolumeControl in #if !os(tvOS) (also fixes pre-existing tvOS build break)
- Ignore .claude/ in git
