feat(sway): add dictate (whisper.cpp) and ocr (tesseract) keybinds

Push-to-talk dictation toggle on Super+i: parecord captures 16 kHz mono
WAV, whisper-cli transcribes (auto language), output is typed via wtype
and copied to the clipboard.

Region OCR on Super+Shift+o: slurp + grim feed tesseract (eng+por),
result lands in the clipboard with a notification preview.

Adds wtype to wayland.txt; tesseract (+eng/por data) and whisper.cpp +
the large-v3-turbo-q5_0 model package to extra.txt.
