Address remaining review items (queue, selfbot v6 API, ldconfig, resample)

- voice.ts: reply playback is now a FIFO queue (AudioPlayerStatus.Idle drains
  it) so concurrent speakers no longer cut each other's replies off.
- selfbot.ts: rewritten against the REAL @dank074/discord-video-stream v6 API
  (verified from its d.ts): prepareStream(input, opts, signal)->{command,output},
  playStream(output, streamer, {type:"go-live"}, signal), Streamer.joinVoice.
  x11grab via customInputOptions; optional NVENC encode (RTX 5050) via exported
  `nvenc`. package.json pinned to ^6.0.0 (was a wrong ^4.2.1).
- Dockerfile: dropped the hardcoded python3.12 LD_LIBRARY_PATH. faster-whisper
  >=1.1 self-locates the pip CUDA libs; ldconfig (full path, glob) registers
  them as a robust fallback. Verified: ld.so cache lists libcublas/libcudnn and
  GPU whisper works with LD_LIBRARY_PATH empty.
- bridge: STT resample 48k->16k upgraded from nearest-neighbor to linear
  (np.interp).

Verified: tsc clean, image builds, GPU whisper OK via ldconfig, compose valid.
