Recolor art work project

This is the GOSC '25 Project.

Project Overview

This project adds a new Recolor Artwork feature to Inkscape. The tool allows users to:

• Group colors: When selecting multiple objects with different colors, any identical or very similar colors are grouped into a single slot.
• Replace colors: Users can assign alternative colors to each slot, making it easy to recolor complex artwork consistently.
• Live preview: A toggleable Live Preview option lets users immediately see changes applied to their selection, improving workflow efficiency and reducing trial-and-error
  • onHover Effect hover on color slots to highlight objects with theses colors here at this MR #7424

    • fe color flood - handle as normal color + opacity convertion (future feature)
    • Color Metrix - not sure if this is possible since this is becialy color manipulator. we would need to do something crazy like reading input first, then semple resulted color somehow and then convert slider cahnges to this manipulators defintly posible but probably not wortf the trouble and complexity (future feature)
