Schedule X posts, and connect more than one account

X threads can now go out on a schedule, to a specific connected account. Personal settings also live in one dialog.

System publish is no longer immediate-only.

Pick a time for an X thread; it goes out then, and you can reschedule or cancel. The topic dialog and operations both work.
Connect more than one X account to the same MuseCanto user, then choose which account a draft should hit. One draft still publishes to one account.
Personal settings open from the sidebar: general, security, billing, tokens, and integrations.
Docs, blog, and changelog live as MDX in the repo; the extension install guide and import / export API pages are also more complete.

System publish still needs Pro or above. Already-published threads cannot be scheduled again. Same day: write X posts on the calendar and send them from there.
