Subject: [PATCH] fix(bot): stop the main slot handing out a dead link, add PEX
 to the live menu
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MINI_APP_URLS.main still pointed at telegram.pezkuwichain.io, the testnet domain
whose DNS record was removed on 2026-07-12. Live webhooks arrive as ?bot=krd and
?bot=dks so that default is never reached today, but a webhook call without the
parameter would have answered /start with a link that cannot resolve.

Also puts the PEX.network link on the krd menu — @pezkuwichainBot, the bot that
actually opens the mini app. It only existed on the dks welcome, so no user
reaching the mini app through the main bot has ever been shown it.

Leaves the three-slot routing alone: both slots are live and healthy on the
cloud project, and collapsing them would have removed the AI assistant.
