Dev build for testers — aarch64 Linux support, plus radio fixes.
Changes since v0.9.1-dev.4:
Linux (new): aarch64 / ARM64 AppImages are now published alongside x86_64 — for Asahi Linux, Raspberry Pi, and other ARM systems (#5). The in-app updater automatically picks the build matching your architecture.
Radio: album art no longer flickers or re-downloads when you seek; art lookups are limited to a real "Artist - Title" and unrelated iTunes matches are rejected (no more random "greatest hits" covers during ads); and Now Playing is cast-aware — play/pause reflects and drives the cast device, and the local rewind/skip/live controls hide while casting.
Desktop builds attached below: Fathom-x86_64.AppImage, Fathom-aarch64.AppImage, and the Windows zip. Please report anything that looks off.
