Trying some new oxlint optimizations. This PR has gone over several iterations in the last few months and the core idea is simple: don't run rules for files if they don't apply (using an AST node bitset lookup). The result: linting is around 15% faster in practice.

github.com/oxc-project/... Note that this is still very much a work in progress. Probably won't be merged for a bit as the hard part is ensuring correctness when skipping rules.

Idea: ship it where you make your predictions about the rules that cannot possibly apply and if any is matched you report the transgression via telemetry.
