Pull request overview

This PR adds a "Recent Projects" section to the "Open Project" dialog (command palette), allowing users to quickly access their recently opened projects without needing to browse the full file system. The implementation adds recent projects as a grouped section at the top of the directory selection list, which can be searched alongside regular folder results.

Changes:

• Added recent projects grouping in the directory selection dialog with deduplication logic
• Added translation keys for project switching and recent projects in 16 language files
• Integrated layout context to access the project list in the dialog component
