feat(lexer): detect Webpack entry exports in extended mode

README.md

@@ -111,9 +111,17 @@ The same limitation applies to `Object.defineProperties`.
 Direct reexport assignments contribute all detected dependencies instead of only the last assignment.
 Object spreads of `require('literal')` contribute reexports, but named properties with require-valued expressions do not.
 
+Extended mode recognizes Webpack assignments through `__webpack_exports__` and getter maps in `__webpack_require__.d`.
+For object-shaped `__webpack_modules__` tables, a literal startup module ID selects the entry factory.
+Detection follows internal whole-module reexports and supported star reexports, which exclude `default` and `__esModule`.
+An inlined entry can instead initialize `__webpack_exports__` with an object literal.
+Unrelated factories do not contribute names when the bundle publishes the recognized entry.
+Unrecognized startup expressions and unresolved internal reexports retain candidate detection.

 The result contains syntactic candidates, which can include non-enumerable properties, throwing getters, and unreachable assignments.
 Extended mode does not apply the default getter side-effect veto.
-It does not resolve bindings or aliases, evaluate computed names, or determine runtime control flow.
+It recognizes Webpack factory parameters but does not generally resolve bindings or aliases.
+It does not evaluate computed names or determine runtime control flow.
 Names created by dynamic expressions can therefore remain undetected, and shadowed identifiers can produce false positives.
 
 Division and regular-expression detection remains heuristic.
