Create workspace from issue

You can now create workspaces from Linear or GitHub issues through the "Create from..." dropdown (⌘I).

The old ⌘⇧N dialog is gone.

Improvements

• Built-in slash commands like /compact, /clear, and /plan now insert into the composer when selected from the autocomplete menu and send on a second Enter, matching custom commands and skills.
• Added a refresh button for Linear auth.

Fixes

• Fixed an issue where the agent's workspace diff could compare against the wrong base branch for PRs targeting a non-default branch.
• The Run and Setup tabs now pick up .conductor/settings.toml changes without an app restart.
• Fixed an .internal/node_modules failed to start error.
• Fixed an issue where a dialog would stay open after navigating away.
