v0.4.0

What's new

• Automatic microphone recovery: when your mic disconnects, HushMic falls back to the system default and switches back on its own when the mic returns.
• Per-microphone preferences: each microphone remembers its own model and suppression strength, and the tray follows whichever mic is active.
• Built-in diagnostics: run hushmic --doctor (or click Copy diagnostics in the About window) for a paste-ready report covering versions, devices, and the recent processing log.
• Mic test polish: the A/B window follows mic changes live while it is open, and tells you when a selected device is delivering no audio at all (a switched-off wireless headset, for example).

Fixes

• The A/B window no longer stays locked to the microphone it was opened with; Retry detection genuinely re-detects now.
• Opening the mic test window is robust against transient PipeWire probe failures on busy systems.
• Notices in the mic test window stay up long enough to read; the About card is a single clean action.

Compatibility — x86-64, glibc 2.35+ (Ubuntu 22.04, Debian 12, and newer). Tested on Ubuntu 22.04, Debian 12, Linux Mint 22.1, Fedora Kinoite, and Arch.

Upgrading — re-download the AppImage, apt install the new .deb, or re-run the install script; your ~/.config/hushmic settings are kept.

Verify — each artifact's SHA-256 is in sha256sums.txt below; the install script checks it automatically.
