feat(desktop): add CMD+P quick open file command palette

[Kitenite]

Summary

• Adds a VS Code-style CMD+P (Ctrl+Shift+P on Windows/Linux) command palette for fuzzy-searching and opening files in the current workspace worktree
• Reuses existing useFileSearch hook (Fuse.js backend) and CommandDialog from @superset/ui
• Selecting a file opens it via addFileViewerPane using relativePath, matching sidebar behavior

Test plan

• Press CMD+P in a workspace — dialog opens
• Type a filename — results appear with fuzzy matching and file icons
• Arrow keys to navigate, Enter to select — file opens in a viewer pane
• Escape to close — dialog closes, query resets
• Press CMD+P again — dialog opens fresh (no stale query)
• Verify Ctrl+Shift+P works on Linux/Windows

Summary by CodeRabbit

• New Features
  • Introduced Command Palette for quickly searching and opening files within the workspace. Access it using Cmd+P (Mac) or Ctrl+P (Windows/Linux). Results display file icons and paths for easy identification.

📝 Walkthrough

Walkthrough

This PR introduces a Command Palette feature enabling quick file search and navigation. It adds a new CommandPalette React component, a useCommandPalette hook managing state and integrating with file search and tabs store, binds the feature to a meta+p hotkey, and wires it into the workspace route.

Changes

Cohort / File(s)	Summary
Command Palette Component & Hook apps/desktop/src/renderer/screens/main/components/CommandPalette/CommandPalette.tsx, apps/desktop/src/renderer/screens/main/components/CommandPalette/useCommandPalette.ts, apps/desktop/src/renderer/screens/main/components/CommandPalette/index.ts	New CommandPalette React component rendering a search dialog with file results and file icon display. useCommandPalette hook manages open/query state, debounced file search, file selection (adding to tabs store), and toggle/close logic. Index exports both the component and hook.
Workspace Route Integration apps/desktop/src/renderer/routes/_authenticated/_dashboard/workspace/$workspaceId/page.tsx	Integrates CommandPalette component and hook into the workspace page. Initializes palette with workspace context, binds QUICK_OPEN hotkey to toggle, and wires state and callbacks to the CommandPalette component.
Hotkeys Configuration apps/desktop/src/shared/hotkeys.ts	Adds QUICK_OPEN hotkey definition (meta+p) with navigation category and quick-open file search description.

🐰 whisker-twitch of glee
With meta and P, the palette takes flight,
Files leap to our paws in search-powered light!
Quick-open magic for dev-kind so fleet,
Another fine feature, the PR's complete! ✨
