[CommandPalette] Add Storybook stories

[Rohitgautam02]

Description

Added Storybook stories for the CommandPalette component which was missing documentation.

Relevant Technical Choices

Added 5 stories covering all component features:

• Default - Basic command palette with navigation items and search filtering
• MultipleGroups - Multiple grouped sections (Pages, Actions, Settings)
• WithDisabledItems - Demonstrates disabled item behavior
• HiddenGroupTitle - Uses hideTitle: true to hide group headers
• KeyboardShortcut - Demonstrates the Ctrl+K keyboard shortcut to open the palette

Followed existing story patterns from other components (Dialog, Combobox, Badge).

Testing Instructions

1. Run pnpm storybook
2. Navigate to Components → CommandPalette
3. Verify all 5 stories render correctly
4. Test search filtering in each story
5. Test the Ctrl+K keyboard shortcut in the KeyboardShortcut story

Additional Information

This is a documentation improvement. All checks pass:

• pnpm lint:types - clean
• pnpm lint:js - no errors from new file
• pnpm build-storybook - builds successfully

Addressed all review feedback from Copilot:

• Replaced alert() with action("onSelect") from storybook/actions — selections now appear in the Storybook Actions panel without blocking the UI
• Extracted filterGroups() helper to eliminate duplicated filtering logic across all stories
• Updated keyboard shortcut text from "Ctrl" to "Ctrl/Cmd" to match the component's support for both ctrlKey and metaKey
• Moved inline data in HiddenGroupTitle story to a top-level constant for consistency

Commit is now GPG-signed and verified.

Also, please resolve the Copilot review yourself if you have addressed it.
