/**
 * Typing Indicator — sends Telegram "typing..." action for the full
 * duration the agent is thinking/processing.
 *
 * Telegram's `sendChatAction` typing indicator expires after ~5 seconds,
 * so we re-send it every 4.5s on a loop until explicitly stopped.
 *
 * Follows the same raw Bot API call pattern as telegram-draft-stream.ts.
 * No new dependencies — uses guardedFetch.
 *
 * Lifecycle:
 *   message_received → start(chatId)
 *   message_sending  → stop(chatId)
 *
 * Safety:
 *   - Max duration cap (5 minutes) prevents orphaned indicators
 *   - Errors are swallowed (typing indicator is non-critical UX)
 *   - Only activates for Telegram channel
