Fader 0.21.0

Fader no longer keeps per-app aggregate IO running forever. Idle taps park safely, Core Audio may let the CPU sleep, and playback resumes with the saved volume and route intact. This release also stops apps from briefly jumping to full volume while Fader rebuilds their audio path after an output change, a new helper process, or a Bluetooth reconnect, and folds in the lifecycle hardening and the fix for the false Audio Capture permission banner.
