Support multi-editor selection in 'vp create' interactive flow

[sanathusk]

The current 'vp create' flow only allows users to select a single editor configuration (VSCode, Zed, or None) at 'editor.ts:160-207'. This limitation forces developers who work with multiple editors to either:

• Choose only one editor configuration
• Manually copy configurations after project creation
• Run the create command multiple times with different editor flags

Proposed Solution

Enable multi-editor selection in the 'vp create' interactive flow, allowing users to generate configuration files for multiple editors simultaneously.
