2026.06.15: fix(cli): handle crossfade mode 5 (always) in settings sync

[tsirysndr]

[2026.06.15]

Added

• rockboxd login <handle> — OAuth login to Rocksky using your Bluesky handle; opens the authorisation URL in the default browser and spins up a minimal tokio TCP server on port 6996 to receive the callback token, which is persisted to ~/.config/rockbox.org/token
• rockboxd whoami — print the currently logged-in Rocksky user (reads the stored token and resolves the handle via the Rocksky API)
• rockboxd settings pull [--did <DID_OR_HANDLE>] — fetch audio settings (equalizer, crossfade, replaygain, tone/bass/treble/balance/channels) from Rocksky and merge them into ~/.config/rockbox.org/settings.toml without touching any other fields; --did enables public access — any user's settings can be pulled without a token by passing their DID or handle
• rockboxd settings push — read the current settings.toml and upload the audio sections (equalizer, crossfade, replaygain, tone) to Rocksky via app.rocksky.rockbox.putAudioSettings; requires a valid stored token
• All four subcommands exit the process immediately after completing — the Zig firmware and gRPC/HTTP servers are never started, avoiding the C-global-initialisation segfault that would occur before main_c() runs
