Two fixes for the CommonJS cycle check and the bundled-chunk splitter:
- During a cycle's initialization, a read of a partner's exported
function is safe only where the value neither runs nor stays: an
expression statement, typeof, void, !, an equality operand, or the test
of if, while, do and ?:. A const alias (`const f = binding.fn`), an
object or array literal, a return, or an argument can be called before
the cycle settles, so these keep SC1016 (Node throws when the function
reads a binding in its temporal dead zone). A top-level const that only
publishes the function in an export statement, as the static rewrite
spells an export-table re-export, stays a read.
- A copied helper whose initializer is a named function expression
reaches itself through its own name. Each chunk gets its own copy, so
that name must also be used only as a callee; otherwise the chunk keeps
the package refused with the existing reason.
