Bytecode modules now load correctly in sandbox mode. HS .sxbc modules
use K.load('(load-sxbc ...)') which syncs defines to eval env. Web stack
.sxbc modules use K.loadModule with import suspension drive loop.
K.eval used directly for expression eval (not thunk wrapper) so bytecode-
defined symbols are visible. Falls back to callFn thunk on IO suspension.
Sandbox now reproduces the bytecode repeat bug: source gives 6/6
suspensions, bytecode gives 4/6. Bug is in bytecode compilation of
when/do across perform boundaries, not the runtime wrapper.
