These are OCaml-side bookkeeping for the Python async bridge. The browser
WASM kernel registers them in the CEK env but not the VM global table,
so bytecode-compiled batch() crashed with "VM undefined: batch-begin!".
The SX-level *batch-depth*/*batch-queue* already handle batching correctly.
Verified in Playwright sandbox: signal, deref, reset!, batch, computed
all work with source fallback (sxbc load-format issue is pre-existing).
