✨ feat: Add global search across all projects (⌘K command palette)

[fulviofreitas]

Hi @thomas-pedersen! 👋

First of all, thank you for creating this fantastic tool! I've been using Cursor Chat Browser daily to review my AI conversations, and it's been incredibly helpful for my workflow.

While using the app, I found myself frequently wanting to search across all my projects at once rather than navigating to each workspace individually. So I built a global search feature that I think could benefit other users too!

✨ What This PR Adds

A command palette-style global search that lets users instantly find any conversation across all their workspaces:

to open from anywhere!

Key Features

Feature	Description
🎹 Keyboard Shortcut	⌘K (Mac) / Ctrl+K (Windows/Linux) to open instantly
⚡ Real-time Search	Results appear as you type (300ms debounce for performance)
🎯 Filter Tabs	Filter by All, Ask Logs, or Agent Logs
⌨️ Keyboard Navigation	↑/↓ to navigate, Enter to open, Esc to close
📝 Context Snippets	Shows matching text with surrounding context
🎨 Beautiful UI	Command palette design matching modern dev tools

Technical Improvements

This PR also includes an important fix to the search API:

• Updated to support new Cursor data format - The search now queries the cursorDiskKV table where newer Cursor versions store data (keys like composerData:* and bubbleId:*)
• Backward compatibility maintained - Still searches the old ItemTable format for older data
• Proper text extraction - Uses the same bubble parsing logic as the tabs route
• Deduplication - Removes duplicate results

Files Changed

File	Change
src/components/global-search.tsx	New command palette search component
src/components/ui/dialog.tsx	New Radix UI dialog component
src/components/navbar.tsx	Added search button to navbar
src/app/api/search/route.ts	Fixed search to support new data format

New Dependency

• @radix-ui/react-dialog - For the modal dialog (consistent with your existing Radix UI usage)

🧪 Testing

I've tested this on:

• ✅ macOS with latest Cursor version
• ✅ Both light and dark themes
• ✅ Keyboard-only navigation
• ✅ Various search queries across multiple projects

💭 Why I Think This Would Be Valuable

1. Saves time - No need to remember which project a conversation was in
2. Familiar UX - Command palette is a pattern developers love (VS Code, Cursor, Raycast, etc.)
3. Accessible - Full keyboard support for power users
4. Non-intrusive - Doesn't change existing functionality, just adds to it

I'd be happy to make any adjustments based on your feedback! Whether it's code style changes, feature modifications, or anything else—just let me know.

Thanks again for your work on this project! 🙏

Best regards,
Fulvio
