* feat(telegram): support custom apiRoot for alternative API endpoints
Add `apiRoot` config option to allow users to specify custom Telegram Bot
API endpoints (e.g., self-hosted Bot API servers). Threads the configured
base URL through all Telegram API call sites: bot creation, send, probe,
audit, media download, and api-fetch. Extends SSRF policy to dynamically
trust custom apiRoot hostname for media downloads.
Closes#28535

* fix(telegram): persist sticky IPv4 fallback across polling restarts (fixes#48177)
Hoist resolveTelegramTransport() out of createTelegramBot() so the
transport (and its sticky IPv4 fallback state) persists across polling
restarts. Previously, each polling restart created a new transport with
stickyIpv4FallbackEnabled=false, causing repeated IPv6 timeouts on
hosts with unstable IPv6 connectivity.
Changes:
- bot.ts: accept optional telegramTransport in TelegramBotOptions
- monitor.ts: resolve transport once before polling loop
- polling-session.ts: pass transport through to bot creation
AI-assisted (Claude Sonnet 4). Tested: tsc --noEmit clean.
* Update extensions/telegram/src/polling-session.ts
