chore: upgrade xo to 2.0

[MattPark]

Summary

• Bumps xo from ^1.1.0 to ^2.0.2 (ESLint 10)
• Suppresses new rules that fire on legacy jQuery code (require-unicode-regexp, unicorn/no-immediate-mutation, @stylistic/curly-newline, unicorn/no-array-sort, max-lines)
• yarn test passes cleanly (6 warnings only — long lines in legacy files)

Closes #8879

Notes

The suppressed rules all fire exclusively on core.js (4500-line legacy jQuery file) which will eventually be replaced by the webpack frontend. Not worth refactoring now.
