Module fixture 

Fixture system: dependency-injected, scoped, auto-teardown.

Built-in fixtures: browser (worker scope), context (test scope), page (test scope). Custom fixtures can depend on built-ins and each other, forming a DAG.

Uses lock-free DashMap for fixture values — zero contention on concurrent reads.
