Chat mode becomes threads in your workspaces, and Bridge can find any session

Added

• Ask Bridge "where is the agent working on the login tests?" and it finds the session — a terminal pane in any workspace, a saved agent's chat or a Chat-mode thread — takes you there, highlights it, and tells you what it was last doing; when two fit it names them and asks. Bridge can also list every workspace, tab and pane at once.
• Chat mode is now threads in your workspaces, the way T3 Code works: the sidebar lists your folders, each thread underneath is one coding session in that folder, and a new thread starts from the folder's +, the header's +, or Ctrl+N.
• Cursor, Grok Build and OpenCode can run a thread alongside Claude Code and Codex, through each CLI's Agent Client Protocol; the model menu lists what the agent reports, and the agent's permission asks appear above the composer with Allow / Allow for session / Deny.
• Each thread's header names its folder, git branch, engine and model, and a Changes panel shows the workspace's changed files with a unified diff per file, refreshing when a turn finishes.
• Pin a thread to keep it above every folder, and a thread that finishes while you are elsewhere shows an unread dot until you open it.
• Muse Code by Meta can be launched as a coding agent in terminal panes and workspace lineups.

Changed

• Chats written before threads had folders still open and run; they list under "Other chats" at the bottom of the rail.
• A terminal handoff aimed at a chat engine now opens a Chat-mode thread in the workspace instead of a pane beside the terminal.
• The browser tab that finishes sign-in now shows a BridgeMind page saying you're signed in (or that sign-in didn't finish) instead of a bare line of text.

Fixed

• When an update downloads but the installer cannot start, the title-bar pill now says the update failed and offers a retry instead of silently showing "Update" again, and Settings › Software update adds a Download installer button that opens the current signed Windows installer in your browser so you can finish by hand.

Removed

• The Thread pane is gone from Code mode's + menu and Alt+T; a thread is a Chat-mode conversation in the folder now, and a saved layout that still holds one shows a card that opens Chat mode instead.
