pair gives Neovim coding agents a voice

Field notes

After `pair init`, the session runs through a terminal workflow: F5 records speech until a pause or a second press, while F6 interrupts and opens the mic. Neovim highlights additions and removals, and hand edits are diffed into the next prompt. Audio transcription uses a locally downloaded 1.6 GB whisper.cpp model; the page says releases, checksums, and the Homebrew cask are public, while the source remains private.
