Posts can now be sourced from multiple VK groups, each routed to its own
Telegram/MAX destination(s) with independent on/off switches, configured
via data/routes.json (supports // line comments). Falls back to a single
route auto-generated from the legacy VK_SOURCE/TG_CHAT_ID/MAX_CHAT_ID env
vars if routes.json doesn't exist yet, so existing deployments keep working.
Routes are processed strictly sequentially within a cycle (no concurrency)
to keep flood control on VK/TG/MAX correct, since bot tokens are shared
across routes. DB schema gains route_id in the posts uniqueness key so the
same VK donor can safely feed multiple routes without status collisions.
Also removes the trailing-hashtag-stripping logic in text_formatter, which
was silently deleting VK posts' own hashtags whenever COMMON_TAGS wasn't
configured (it always wasn't) - posts are now forwarded unchanged.
- Stop blindly retrying send_photo/send_video/send_media_group and MAX
send_message on ambiguous network timeouts - a timeout doesn't prove
the message wasn't delivered, and retrying risked posting duplicates
(observed live: a video posted 3-5x after repeated timeout retries).
- Raise/rework timeouts that were too short for real large-file transfer
speeds: TG media upload timeout, and yt-dlp download now uses stall
detection (killed only on true silence) instead of a flat ceiling that
was cutting off legitimately slow-but-successful video downloads.
- Fix sendRichMessage: ok=true with an unparseable message_id no longer
triggers a fallback send (Telegram already created the message).
- MAX: videos over the documented 250MB cap are now sent as a "watch via
link" note instead of silently failing the upload.
- Add PRAGMA busy_timeout to all DB connections.
- Remove unused MAX_MEDIA_CHANNEL_ID (MAX's /uploads returns a portable
token directly, no staging channel needed, unlike Telegram).

MAX Bot API has no reaction endpoint (confirmed 404 in production logs),
so drop the dead code path entirely instead of eating a warning every post.
Telegram's setMessageReaction is a real Bot API method (verified against
aiogram 3.21.0, the pinned version) - wire it up as a non-fatal
best-effort call after a successful send, mirroring the same
try/except-and-log pattern MAX already used.
- Stop re-sending to a platform that already succeeded when the other
platform failed (was causing duplicate posts on partial failure)
- Escape VK post text before sending with parse_mode=HTML instead of
only escaping matched bracket-link substrings (bare & < > broke sends)
- Restore Telegram sendRichMessage (Bot API 10.1) ported faithfully from
new_vk_parser's proven implementation, with fallback to standard
send_photo/send_video/send_media_group
- Restore "media unavailable" note when a video/photo fails to download
instead of silently dropping it
- Handle YouTube link attachments from VK posts (route into yt-dlp)
- MAX: chunk media beyond 10 items into follow-up messages instead of
dropping them
- yt-dlp format selector no longer falls back to unconstrained height
- Wire up VK_RATE_LIMIT_RPS, drop unused Pillow dep and dead config fields
