feat: add Typer CLI with daemon mode and wtype keyboard injection

Replace argparse CLI with Typer-based CLI supporting `cohere on/off/status`
commands. The daemon runs transcription in the background and types into the
focused Wayland window via wtype. Adds wtype to flake.nix and fixes the
hatchling build backend.
