Summary

Adds a command dialog for adding projects via keyboard shortcut (Mod+Shift+K) with filesystem path autocomplete. Type a path, Tab to autocomplete directories, Enter to add the project.

This is marked as draft because I don't want to waste anyone's time with my opinions, but this UX makes me and several people I know significantly more productive when working with multiple projects. This also lays the groundwork for a command palette pattern that could later be extended for searching existing projects and selecting threads. Apologies if this feels like an opinionated addition, totally understand if it's not the direction you'd like to go. No hard feelings if this gets closed, just a personal preference that I thought was worth sharing. When you have time to consider it, I'd really appreciate a look.

if this gets approved, happy to add existing project search + selecting threads in same dialog

Changes

• New filesystem.browse WS method that lists directories at a given partial path
• project.addByPath keybinding command (Mod+Shift+K)
• AddProjectDialog component using existing Command UI primitives
• Integration in the chat route layout

How it works

• Mod+Shift+K opens the dialog (works even with zero projects)
• Typing a path (e.g. ~/) fetches matching directories from the server
• Tab: drills into the highlighted directory (autocomplete)
• Enter: adds the highlighted directory (or typed path) as a project
• ArrowUp/ArrowDown: navigate the suggestions
• Escape: closes the dialog
• Supports ~ expansion, hidden file filtering, debounced requests

Test plan

• Mod+Shift+K opens the dialog
• Typing ~/ shows home directory contents
• Tab completes the highlighted directory
• Enter on highlighted directory adds it as a project
• Enter on typed path adds it as a project
• Escape closes the dialog
• Existing file picker still works via sidebar button
