hypr: add hold-to-talk voice dictation via whisrs

Bind the Copilot key (SUPER+SHIFT+F23) to whisrs on press and release,
so holding it records and letting go transcribes. Injection uses wtype,
which works natively on Hyprland and reaches any focused window,
including TUIs running in the dockerized agent containers.

Decoding runs on the iGPU through the Vulkan feature of a locally
rebuilt whisrs-git: the stock AUR build is CPU-only and compiled with
generic -march, which made dictation take around five seconds. Requires
whisrs-git (AUR), wtype and pipewire-alsa; documented in the README
along with the config and model locations.
