refactor: optimize by loading only required graph features

[tbouffard]

Create CustomGraph that registers only the features needed by our examples instead of loading all built-in styles and shapes.

This prepares for future tree-shaking improvements in maxGraph which will reduce bundle size.

Notes

Covers maxGraph/maxGraph#760

Bundle sizes

Note

The new implementation sightly increase the size of the bundle, mainly because it:

• now includes the declaration of the builtin styles and plugins used by the application
• temporary includes the implementation of EdgeMarker.createArrow which is not exported by maxGraph 0.17.0. It will be removed when using maxGraph 0.18.0 which exports it.

Example	defaults	selected features
farm	453.9 kB	454.2 kB
lit with vite	461.5 kB	462.4 kB
parcel	528.1 KB	529.3 kB
rollup	438.3 kB	439.2 kB
rsbuild	417.3 kB	416.9 kB
vite	442.2 kB	443.1 kB
