Music:
- #random URL fragment shuffles playlist tracks before enqueuing
- Lazy playlist resolution: first 10 tracks resolve immediately,
remaining are fetched in a background task
- !kept repair re-downloads kept tracks with missing local files
- !kept shows [MISSING] marker for tracks without local files
- TTS ducking: music ducks when merlin speaks via voice peer,
smooth restore after TTS finishes
Performance (from profiling):
- Connection pool: preload_content=True for SOCKS connection reuse
- Pool tuning: 30 pools / 8 connections (up from 20/4)
- _PooledResponse wrapper for stdlib-compatible read interface
- Iterative _extract_videos (replace 51K-deep recursion with stack)
- proxy=False for local SearXNG
Voice + multi-bot:
- Per-bot voice config lookup ([<username>.voice] in TOML)
- Mute detection: skip duck silence when all users muted
- Autoplay shuffle deck (no repeats until full cycle)
- Seek clamp to track duration (prevent seek-past-end stall)

- Add rubberband package to container for pitch-shifting FX
- Split FX chain: rubberband CLI for pitch, ffmpeg for filters
- Configurable voice profile (voice, fx, piper params) in [voice]
- Extra bots inherit voice config (minus trigger) for own TTS
- Greeting is voice-only, spoken directly by the greeting bot
- Per-bot only_plugins/except_plugins filtering on Mumble
- Alias plugin, core plugin tests

- Add fade_step parameter to stream_audio for fast volume ramps
- _fade_and_cancel helper: smooth ~0.8s fade before track switch
- !skip, !stop, !seek now fade out instead of cutting instantly
- !prev command: go back to previous track (10-track history stack)
- !keep fetches title/artist/duration via yt-dlp, stores in bot.state
- !kept displays metadata (title, artist, duration, file size)
- !kept clear also removes stored metadata
- 29 new tests for fade, prev, history, keep metadata

The else branch (no active task) only cleared current, task, and
duck_vol. Now resets all play state fields to match _play_loop's
finally block: done_event, duck_task, progress, and cur_seek.

task.cancel() triggers _play_loop's finally block asynchronously.
When cmd_skip or cmd_seek called _ensure_loop before the finally
block ran, the old task's cleanup would overwrite the new task's
state -- causing !np to report "Nothing playing" while audio
was still streaming.
Now await the cancelled task before restarting the loop, ensuring
the finally block completes first.

Seek to absolute or relative positions mid-track via !seek. Supports
M:SS and plain seconds with +/- prefixes. Volume is now saved to
bot.state and restored on connect.
Audio is now downloaded to data/music/ before playback begins,
eliminating CDN hiccups mid-stream. Falls back to streaming on
download failure. Files are deleted after playback unless marked
with !keep. stream_audio detects local files and uses a direct
ffmpeg pipeline (no yt-dlp).
Guard stream_audio with _is_audio_ready() so that PCM frames are
dropped (not crashed on) when pymumble recreates SoundOutput with
encoder=None during reconnect. The ffmpeg pipeline stays alive,
position tracking remains accurate, and audio feeding resumes once
the codec is negotiated. Listeners hear brief silence instead of
a 30+ second restart with URL re-resolution.
Also adds chat messages to _auto_resume so users see what the bot
intends ("Resuming 'X' at M:SS in a moment" / "...aborted").
Auto-resume: save playback position on stream errors and cancellation,
restore automatically after reconnect or container restart once the
channel is silent. Plugin lifecycle hook (on_connected) ensures the
reconnect watcher starts without waiting for user commands.
Sorcerer tier: new permission level between oper and admin. Configured
via [mumble] sorcerers list in derp.toml.
Mumble cert auth: pass certfile/keyfile to pymumble for client
certificate authentication.
Fixes: stream_audio now re-raises CancelledError and Exception so
_play_loop detects failures correctly. Subprocess cleanup uses 3s
timeout. Graceful shutdown cancels background tasks before stopping
pymumble. Safe getattr for _opers in core plugin.

!volume +10 increases by 10, !volume -5 decreases by 5.
Out-of-range results (below 0 or above 100) are rejected.

Tracks playback position via frame counting in stream_audio().
On stop/skip, saves URL + elapsed time to bot.state (SQLite).
!resume reloads the track and seeks to the saved position via
ffmpeg -ss. State persists across bot restarts.

Non-URL input (e.g. !play classical music) searches YouTube for 10
results and picks one randomly. Also fixes --flat-playlist returning
"NA" as the URL for single videos by falling back to the original
input URL.
_resolve_title replaced with _resolve_tracks using --flat-playlist to
enumerate playlist entries. cmd_play enqueues each track individually,
with truncation when the queue is nearly full. Single-video behavior
unchanged.
stream_audio now accepts a callable for volume, re-read on each PCM
frame instead of capturing a static float at track start.

asyncio's SSL memory-BIO transport silently drops voice packets even
though text works fine. pymumble uses blocking ssl.SSLSocket.send()
which reliably delivers voice data.
- Rewrite MumbleBot to use pymumble for connection, SSL, ping, and
voice encoding/sending
- Bridge pymumble thread callbacks to asyncio via
run_coroutine_threadsafe for text dispatch
- Voice via sound_output.add_sound(pcm) -- pymumble handles Opus
encoding, packetization, and timing
- Remove custom protobuf codec, voice varint, and opus ctypes wrapper
- Add container patches for pymumble ssl.wrap_socket (Python 3.13) and
opuslib find_library (musl/Alpine)
