Subject: [PATCH] fix(discord): default standalone threads to public type
 (#14147)

When creating a Discord thread without a messageId (standalone thread),
the Discord API defaults to type 12 (private). Most users expect public.

- Default standalone non-forum threads to ChannelType.PublicThread (11)
- Add optional type field to DiscordThreadCreate for explicit control

Closes #14147
