v0.10.17 is Live — Boards, Terminal Split, and Dark Mode Improvements

Hey everyone! Just shipped v0.10.17 — here's what's new:

- Boards — New /boards slash command with node types, collapsible groups, and node notes

- Terminal Drag-to-Split — Drag to split and unsplit terminal tabs

- Dark Mode & Themes — Refined surface system and improved colors

A quick note: /boards slash command and /api command are currently locked. While using the API command, it locks the agent conversation so the agent can use the tool set. To exit, just type "/exit" and it will return to the default mode.

Would love to hear your thoughts — feedback is always welcome!
