ESLint 10 upgrade deferred

[testower]

Analysis by Claude:

The Renovate PR upgrading eslint (9 → 10) and @eslint/js (9 → 10) is being closed because the plugin ecosystem does not yet support ESLint 10 (released Feb 6, 2026).

Runtime crash

ESLint 10 crashes immediately with:

TypeError: Class extends value undefined is not a constructor or null
at @typescript-eslint/utils/dist/ts-eslint/eslint/FlatESLint.js:12:49

• eslint-plugin-import adds support (or consider replacing with eslint-plugin-import-x)
• eslint-plugin-jsx-a11y adds support
