Wiki-link suggestions, Cogito links, draggable tabs, AI chat

New

• Wiki-link suggestions — type [[ in source mode to search and insert links to other notes without leaving the keyboard.
• Go-to-line — press ⌘L to jump to any line in the current note.
• Cogito links — copy a link to any note or line via the Copy Cogito Link menu items, or press ⌘⇧. for the current note. Open links like cogito://open?path=/Notes/ideas.md&line=42 from anywhere to land on the exact spot.
• Drag-to-reorder tabs — rearrange open tabs by dragging, with live visual feedback as neighbors slide out of the way.
• Tab navigation shortcuts — cycle through tabs with Ctrl+Tab / Ctrl+Shift+Tab, or use ⌘⇧] / ⌘⇧[ and ⌘⌥→ / ⌘⌥←.
• AI chat (experimental) — a right-hand sidebar for local AI conversations about your notes, backed by Claude Code or Codex CLI. Enable in Settings > Experimental.

Improved

• Typing in long notes stays smooth even in very large documents.
• Window resize no longer stutters — layout work is deferred until the drag ends.
• Opening files from Finder or other apps creates a new tab instead of replacing your current note. If no window is open, one is created automatically.
• Note open and sidebar updates are snappier, with less redundant work after renames, moves, and file operations.

Fixed

• Indented fenced code blocks now recognized correctly in source mode.
• Opening Location files no longer flashes a blank window.
• Tab-switch animations no longer bleed into sidebar rows.
• Folder expand/collapse animations restored in the sidebar.
• Sidebar rows no longer ghost briefly during autosave.
• Paragraph layout stays responsive during window resize.
