* fix(javascript): keep members unknown after a write through a local setter
Assigning to a key that a setter of the binding's own object literal
defines runs that setter, which may replace any member of its receiver.
The member-mutation collector recorded it as an ordinary write to that
one key, so sibling literals such as value: 1 stayed known and
export-shape comparisons reported complete, unchanged shapes.
Record such a write with an unknown key, which invalidates the object's
known members. A computed setter key may match any written key.

* fix(javascript): follow nested setters, skip deletes and cache setter keys
Resolve the written receiver along nested object-literal members so a
write through a nested setter widens that receiver's members. A delete
never calls a setter, so it keeps its exact path. Setter keys are
computed once per object literal, including the no-setter result.

* fix(javascript): ignore setters replaced by a later data property
Build cached setter keys from the effective definitions: a later data
property or method with the same static name replaces the accessor, so
assigning that key no longer runs a setter.
