fixes that were dropping messages:
- d->tg sent parse_mode=Markdown with an unescaped body, so any message
with a stray * _ ` or [ got a 400 from telegram and vanished. now html
with proper escaping + a plain-text retry
- no allowed_mentions on webhook posts, so telegram could @everyone
- forwarder.start() ran from on_ready, which fires again on every gateway
reconnect -> second poller on the same token -> 409s and dupes
- document.mime_type is nullable and was called directly
- sticker finally block hit UnboundLocalError when mkstemp raised
- ffmpeg timeouts leaked temp files and orphaned the process
stickers, per format instead of one blanket gif convert:
- static .webp now passes through (the gif convert crushed 228 alpha
levels to 2 and made the file 4x bigger)
- video .webm -> animated webp, keeps 8-bit alpha, ~7x smaller than gif.
needs -c:v libvpx-vp9 before -i or ffmpeg silently drops the alpha
- .tgs is gzipped lottie, ffmpeg exits 183 on it and we were uploading
the raw file. renders via optional lottie lib, else thumbnail + emoji
added: telegram profile photos as webhook avatars (re-hosted in a private
channel, AVATAR_CACHE_CHANNEL_ID), reply threading both ways, edit sync
both ways, delete sync d->tg, album batching, voice/poll/location/contact/
dice/forward attribution, utf-16-safe entity conversion, mention and custom
emoji resolution, message splitting instead of truncation, shared aiohttp
session with 429 backoff, route discovery from env, !bridge status
main.py just loads the extension now; routes come from credentials.env
