Feature Request: Multi Rename / Bulk Rename

Hello Lunacy Team,

I would like to suggest adding a multi rename (bulk rename) feature for layers and frames.

Feature description:

Allow users to select multiple layers or frames and rename them all at once using a dedicated rename dialog.

Suggested behavior:

- Select multiple items

- Press:

 - Cmd + R (Mac)

 - Ctrl + R (Windows)

- A modal opens with the following options:

 - Find & replace text

 - Add prefix

 - Add suffix

 - Insert sequential numbers (ascending or descending)

Why this is important:

Renaming layers manually is time-consuming, especially in large files with many frames, icons, or repeated elements.  

This feature already exists in tools like Figma and significantly improves workflow speed and file organization.

Use cases:

- Renaming icon sets

- Numbering frames or screens

- Adding consistent prefixes (e.g., "btn_", "icon_", "card_")

- Cleaning up layer names before handoff to developers

This would be a huge productivity boost for everyday design work.

Thank you for considering this feature!
