Teknium b4496b33b5 fix: background task media delivery + vision download timeout (#3919) ...

* feat(telegram): add webhook mode as alternative to polling

When TELEGRAM_WEBHOOK_URL is set, the adapter starts an HTTP webhook
server (via python-telegram-bot's start_webhook()) instead of long
polling. This enables cloud platforms like Fly.io and Railway to
auto-wake suspended machines on inbound HTTP traffic.

Polling remains the default — no behavior change unless the env var
is set.

Env vars:
  TELEGRAM_WEBHOOK_URL    Public HTTPS URL for Telegram to push to
  TELEGRAM_WEBHOOK_PORT   Local listen port (default 8443)
  TELEGRAM_WEBHOOK_SECRET Secret token for update verification

Cherry-picked and adapted from PR #2022 by SHL0MS. Preserved all
current main enhancements (network error recovery, polling conflict
detection, DM topics setup).

* fix: send_document call in background task delivery + vision download timeout

Two fixes salvaged from PR #2269 by amethystani:

1. gateway/run.py: adapter.send_file() → adapter.send_document()
   send_file() doesn't exist on BasePlatformAdapter. Background task
   media files were silently never delivered (AttributeError swallowed
   by except Exception: pass).

2. tools/vision_tools.py: configurable image download timeout via
   HERMES_VISION_DOWNLOAD_TIMEOUT env var (default 30s), plus guard
   against raise None when max_retries=0.

The third fix in #2269 (opencode-go auth config) was already resolved
on main.
