cb-pitch-shift 0.2.2

Changes

• New `cb-pitch-shift-0.2.2-x86_64-ubuntu-26.04.deb` for Ubuntu 26.04 LTS with OBS from the official PPA (`ppa:obsproject/obs-studio`).
• Why a second file: Ubuntu 26.04 renamed the Qt6 runtime packages (`libqt6gui6t64` is now `libqt6gui6`, likewise `libqt6widgets6t64`). The 24.04 `.deb` depends on the old names, so `apt` refuses to install it on 26.04. The new file is built on 26.04 and depends on the right names.
• The README (English, 繁體中文, 日本語) now says which `.deb` to pick.

Existing filter settings and the dock's saved target carry over.
