🟡 Changes recommended

The new filled variant text colors don’t propagate to icons/delete icons due to a conflicting root override, causing incorrect/low-contrast icon coloring on colored chips.

Pull request overview

This PR updates the apollo-react MUI theme override for Chip to style semantic color variants using MUI’s own Chip color/variant CSS classes, improving consistency for primary/secondary/success/info/warning/error filled chips.

Changes:

• Switch variant targeting from custom classes (e.g. .warning, .success) to MUI’s MuiChip-filled + MuiChip-colorX class combinations.
• Add explicit filled styling for primary and secondary chips (including hover states).
• Keep outlined colored behavior delegated to MUI’s built-in outlined styling (border/text with transparent fill).

_{"Coverage" is each package's own coverage.include scope (e.g. apollo-core instruments only scripts/). "Packed"/"Unpacked" come from npm pack --dry-run and only cover built packages — "—" means not measured this run (package not affected / not built). "vs main" is the packed (gzipped) delta against the last successful main build (the package-sizes artifact from the Release workflow); "—" there means no main baseline was available this run. The baseline is main's latest build, not this PR's exact merge-base, so it includes any drift since the branch diverged. Packages with no vitest config are omitted.}
