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").
Volume changes now ramp linearly per-sample via _scale_pcm_ramp instead
of jumping abruptly. Each frame steps _cur_vol toward target by at most
0.1, giving ~200ms for a full 0-to-1 sweep. Fast path unchanged when
volume is stable.
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)

Add `proxy` config option to server (IRC), teams, telegram, and mumble
sections. IRC defaults to false (preserving current direct-connect
behavior); all others default to true. The `derp.http` module now
accepts `proxy=True/False` on urlopen, create_connection,
open_connection, and build_opener -- when false, uses stdlib directly.

TCP/TLS connection over SOCKS5 proxy to Mumble servers for text chat.
Minimal varint/field protobuf encoder/decoder (no external dep) handles
Version, Authenticate, Ping, ServerSync, ChannelState, UserState, and
TextMessage message types. MumbleBot exposes the same duck-typed plugin
API as Bot/TeamsBot/TelegramBot. 93 new tests (1470 total).
