LaTeX math, yolo mode, agent-edit undo

New

• LaTeX math in preview — both inline ($...$) and block ($$...$$) math now renders directly in preview, with transparent backgrounds that adapt to light and dark mode.
• New "Full Access" mode for the AI Chat — a third AI permission level grants the agent unrestricted tooling, including MCP servers, skills, and subagents. This makes it even more useful if you're a Claude Code or Codex power user.

Improved

• Undo for agent edits — every file edit made by the AI Chat agents has an Undo button in chat, and in-session edits are reachable via Cmd+Z in the editor.
• Skill names now appear on tool rows in the AI sidebar for easier scanning.

Fixed

• Long notes in preview no longer stop scrolling before the end of the document.
• The welcome view scrolls properly on shorter windows.
