Epic:
Story Points:

Deferred major bump from the 2.5.0 dependency audit. ESLint stayed on the v9 line (^9.39.5) for 2.5.0; Yarn also warns that ESLint 9 is no longer supported.

Description

Upgrade ESLint tooling to v10:

eslint: 9.x → 10.x (latest at audit time: 10.10.0)
@eslint/js: 9.x → 10.x (latest at audit time: 10.0.1)
Review related packages (typescript-eslint, @eslint/eslintrc, @eslint/plugin-kit) for v10 compatibility

Acceptance Criteria

eslint and @eslint/js are on major 10
eslint.config.mjs updated for any ESLint 10 config / flat-config changes
yarn lint passes with no new unexplained violations
yarn test and yarn build still pass
Compatible typescript-eslint (and related) versions are used if required by ESLint 10
