giles 7a1af7a80a WIP: bytecode when/do/perform — host-callback _driveAsync fix + debugging ...

Root cause identified: nested cek_call_or_suspend calls on same VM
overwrite pending_cek. First call suspends (thunk's hs-wait), second
call from synchronous dom-listen callback overwrites before resume.

sandbox host-callback: removed _driveAsync call to prevent duplicate
resume chains. Still 3/6 in Node.js test — issue is in OCaml call
stack nesting, not JS async.

Next: prevent pending_cek overwrite in nested CEK→VM→CEK→VM chains.
