Binder: TextFieldState is bound without members or a way to create it #73

pythonx-compose TextField design (#10 there) uses the state-based overload TextField(state=...) of Compose 1.11 (typing stays in Compose; no Python round trip per key). In the stubs (run 37098191598) androidx/compose/foundation/text/input/__init__.pyi has class TextFieldState: with no members, and nothing returns one.

Needed, under Kotlin names:

1. androidx.compose.foundation.text.input.rememberTextFieldState(initialText = "", initialSelection = ...) (@composable, defaults)
2. the TextFieldState(initialText, initialSelection) constructor (outside a composition)
3. the TextFieldState.text getter (CharSequence; reading it from Python should give a str)
4. the extension functions TextFieldState.setTextAndPlaceCursorAtEnd(String) and TextFieldState.clearText()

First find out why these are missing (package not walked? declined — with which reason? value-class/inline/opt-in?) and fix that cause rather than special-casing TextFieldState.

Completion: a :ksp-fixtures:compose test creates a TextFieldState from Python (both ways), draws TextField(state=s), sets text with setTextAndPlaceCursorAtEnd and reads s.text back as str; the regenerated stubs carry the four members; all modules green.
