New test files expose fundamental evaluator issues:
- define doesn't create self-referencing closures (13 failures)
- let doesn't isolate scope from parent env (2 failures)
- set! doesn't walk scope chain for closed-over vars (3 failures)
- Component calls return kwargs object instead of evaluating body (10 failures)
485/516 passing (94%). Parser tests: 100% pass. Macro tests: 96% pass.
These failures map the exact work needed for tree-walk removal.
