Resolve event-renderer.ts onRunFinishedEvent: keep the native turn stream open
(finalized in finish()) AND retain the legacy per-message stream drain from main
(#5573) as a no-op-in-native safety net. app/index.ts (telegram adapter from
#5520 + showToolStatus:false) and create-bot.test.ts auto-merged.
examples/slack now starts a Slack bot and/or a Telegram bot from one platform-neutral app layer, env-conditional on which credentials are set. Neutralized Slack-specific rendering so the shared components work on both platforms: unicode glyphs instead of mrkdwn shortcodes, no Block Kit raw fallbacks, neutral context/tool wording. Migrated the Telegram e2e smoke harness and BotFather setup docs; removed the separate examples/telegram app.
