`harness:tick` and `lint:identity` use `node --import tsx` for TypeScript entrypoints, which fails on older Node 20

`node --import` is supported from Node 20.6+. `engines.node` only requires `>=20.0.0`, so a user on 20.0–20.5 will see the harness fail with 'bad option: --import'. Either tighten engines or use `node --loader`/`tsx` directly.
Recommendation
Either bump `engines.node` to `>=20.6.0` (or `>=22`), or invoke `tsx harness/index.ts` directly via the tsx binary.
