* runtime: run syscall/js finalizers on wasm without a manual GC * runtime: address review feedback on finalizer idle GC * runtime: clear a finished task's args pointer so its arguments are collectable * runtime: skip the finalizer scan with a per-block registration bit * runtime: guard the finalizer registration bitmap with gcLock * testdata: cover finalizer invariants on every scheduler * main_test: limit the finalizer scheduler variants to linux and darwin * testdata: wait for the finalizer queue to drain before asserting * testdata: make the finalizer counters atomic and wait for a known drain count * runtime: add finalizer bookkeeping asserts under runtime_asserts * runtime: address finalizer GC review feedback * testdata: strengthen blocked stack finalizer test * runtime: fix finalizer cleanup edge cases * runtime: decouple wasm export scheduling from finalizers * runtime: avoid redundant wakeups for re-entrant wasm exports * runtime: simplify finalizer comments
