Holding this one. The Lint failure is not a code-style violation, ESLint crashes while loading the flat config:

TypeError: mapTypes.union is not a function
    at eslint-plugin-unicorn@73.0.0/rules/utils/builtin-collection-type.js:19:34

@antfu/eslint-config 9.3.0 pulls in eslint-plugin-unicorn 73, whose builtin-collection-type.js calls Set.prototype.union at module scope. That method is ES2025 and only exists on Node 22+, while the Lint job is pinned to node-version: 20 in .github/workflows/ci.yml. Unicorn 73 states the same requirement itself: engines.node >= 22, plus peerDependencies.eslint >= 10.4 against our current eslint 9.39.4.

I rebased onto the current master and re-ran CI, same failure, so this is not a stale base. 73.0.0 is the latest release, there is no patched version to wait for.

Two prerequisites before this can merge, both worth landing on their own rather than inside a dependency bump:

1. Raise the CI Node baseline to 22+ for the lint, typecheck, and build jobs, and revisit the lower bound of the test matrix.
2. Bump eslint from 9 to 10 to satisfy the unicorn peer range.

Leaving the PR open until those are in place.
