Unify all CLI-managed files under ~/.browser-use/ (config, sockets, PIDs,
binaries, tunnels) instead of scattering across ~/.config/browser-use/ and
~/.browser-use/run/. Add profile-use Go binary as managed subcommand via
browser-use profile, with auto-download fallback and install.sh integration.
Wire cloudflared and profile-use availability checks into browser-use doctor.
Login/logout with API key persistence, versioned REST calls (v2/v3),
task polling, and OpenAPI-driven help. Stdlib only, no daemon needed.
