javascript: a call through a field holding a platform-made wrapper reaches the wrapped function

[swapnilpaliwal-sd]

• A field or module variable set to a platform call's result when handed a project function (this.find = promisify(s.find.bind(s))) made this.find() an ambient terminal, so path called the caller independent of the method the wrapper runs.
• Engine (calls.dl): the wrapper call now reaches the bound method when the graph knows it (multi_inferred, beside the platform row). When it does not, the call is an open value callee (unresolved_value_callee). A wrapper of a platform function (promisify(setTimeout), Math.max.bind(Math)) is unchanged.
• path: a call ending on a TypeScript function-type signature counts as a value callee. A value callee named like the other endpoint is listed first and flagged.
• Tests: new rows folded into the existing table-driven cases stored-field-callee-shapes (JS, 3 checks + 2 controls) and function-stored-in-a-holder (TS, 1 check). No new case directories. The 4 new checks fail before and pass after; the controls pass both ways.
• Checked: JS golden 88/88, TS golden 97/97, tests/run.py JS 241/241. TS 168/173: the same 5 fail on the base. Product probes 46→47/70 with no regressions. multi_inferred 356→361, every other tier unchanged. Python, C# and Java were checked on the same shape and already give a chain or a lead.
