/**
 * Zod schemas for inbound webhook payloads.
 * `require-zod-validation-in-routes` requires `await c.req.json()` to be parsed
 * by one of these schemas.
 *
 * Both schemas use `.passthrough()` on nested objects so unmodelled update types
 * (e.g. Slack slash commands, Telegram edited_message, callback_query) continue
 * to flow through and return 200 instead of a 400. Only the fields actually read
 * by the routes are typed explicitly.
