config.spotify is a single process-wide object shared by every BotInstance, so
config.spotify.deviceName was identical for all bots. On the Rust (librespot)
backend each bot spawned `librespot --name <deviceName>` with no per-bot
uniqueness, registering two Connect devices with the same name under the one
shared account. findDeviceByName()/waitForDevice() match by name, so bot A's
transfer()+play() could drive bot B's librespot (misroute) and a bot could
report ready on seeing the OTHER bot's same-named device (false readiness).
Fix: derive a per-bot-unique Connect identity from the shared base name.
- controller.ts: new exported pure helper perBotDeviceName(base, instanceId?)
(`${base}-${instanceId}` when an id is given, else base). Add optional
instanceId to SpotifyControllerOptions; buildBackend() computes the effective
name once and passes the SAME value to both the Rust and go backends so
--name, findDeviceByName, and waitForDevice all key on one identity.
- instance.ts: pass instanceId: this.id into buildController(); add instanceId
to the spotifyControllerFactory param type (test seam).
The user-configured config.spotify.deviceName base is left untouched; the suffix
applies only to the backend/Connect identity. Behavior-preserving for callers
that pass no instanceId (base name used unchanged).

Add the /api/spotify {login,callback,status} router behind the SpotifyOAuthLike
seam (DI-tested with supertest, no network). Build ONE process-wide SpotifyOAuth
in index.ts (clientId/redirectUri from config; store via the already-exported
createFileOAuthTokenStore) and thread that same instance into BOTH createWebServer
AND BotManager -> BotInstance -> SpotifyController, so a web login authorizes
playback (C3.1). Reuses the existing file token store (no token-store.ts).

Construct one SpotifyController per bot (config.spotify + per-bot work/config
dirs under DATA_DIR, threaded via BotManager + index). resolveAndPlay now
routes spotify: sentinels through controller.ensureStarted/playTrack +
player.playPcmStream (falling back to the Stage-1 message when unavailable),
fences/pauses the sidecar on source transitions, advances via controller
"trackEnded", and delegates pause/resume/stop transport. Correction C4:
no re-attach on a spotify->spotify handoff (playPcmStream once across tracks,
no player.stop() — playPcmStream fences the prior ffmpeg internally); occupancy
auto-pause/resume + updateAutoPause + a new BotInstance.seek() (web seek route)
also delegate to the sidecar.

The queue-mutating playback routes (play-now-song, play-next-song,
add-song, play-at) read queue position synchronously, mutate the queue,
then await resolveAndPlay() which suspends at an async URL fetch before
player.play(). With no serialization, two concurrent requests (normal in
login-less guest mode) interleave: the audible song (decided by URL-fetch
latency) can disagree with queue.currentIndex (decided by sync-block
ordering), corrupting "now playing" and causing skipped/duplicate songs.
Add a per-bot async serializer (BotInstance.runExclusive) and wrap the
critical region of all four routes in it. Single-request behavior and
every response shape / validation 400 are preserved; only the critical
region moved inside runExclusive.
