Checks the dedicated Chrome and whether Discord is signed in (logged_in / logged_out / loading) and as which user. Call this first.

Opens and focuses the Discord tab in the dedicated Chrome so the account owner can sign in by hand (one-time; the session persists in that profile). Only navigates to /login when the signed-out state is confirmed.

Lists the open direct conversations in the sidebar (recent-activity order) with their channel_id and whether they have unread messages. Reports whether the sidebar walk was complete.

Reads the most recent messages of a direct conversation, by channel_id (preferred) or by the name shown in discord_list_dms (exactly one of the two). Returns oldest-first messages with local time, author, text, attachments and id, plus hasMore/nextBefore to page back with before. Opening the conversation may mark it as read.

"Look at my messages": walks the conversations with unread messages (up to max_channels, default 5) and returns their latest messages, with per-conversation errors if any and how many were left unprocessed. If nothing is unread, lists the recent conversations.

Closes the Discord tab in the dedicated Chrome (the owner stops appearing online from that browser). It closes by itself after a few minutes of inactivity; call only to force it. Returns closed / busy (another agent is using it) / not_open / chrome_down.
