new colormaps

[lazarusA]

This PR moves us away from using js-colormaps-es and predefined colormap icons. Now all is handle in the browser directly via color-schemes-js with more than 1k colormaps to choose from.

Unfortunately, I could not find an existing package with all the colormaps I would like to have, so I did the port color-schemes-js from the Julia package, ColorSchemes.jl.

This mainly closes #419 (other requests there should be considered in different issues).

The new added package will also allow us to easily do categorical sampling and other advance color shenanigans, see #264 (this should be addressed in a different PR).

Code Review

This pull request replaces the js-colormaps-es dependency with color-schemes-js and introduces a redesigned colormap selection UI featuring search, category filtering, and CSS-based gradient rendering. Feedback focuses on addressing a double-update and double-disposal bug in the Colormaps component's useEffect hook, optimizing a performance bottleneck in resolveColorSchemeName via caching, and adding defensive checks to evaluateColorMap to handle out-of-bounds values and missing schemes safely.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

really nice!

Only changes I would suggest is putting 'Current' next to the name of the current cmap, just keep 'Flip' for the button text, and changing the search bar text to 'Global search' or something to indicate it's not just the current list.
