// getFormState — the canonical "what's on the screen right now" call. Combines:
//   1. DOM script (getFormStateScript) → form structure (fields, buttons, tables, openForms, ...)
//   2. checkForErrors → state.errors + state.confirmation hint
//   3. detectPlatformDialogs → state.platformDialogs (About / Support Info / Error Report)
//
// Returned by virtually every action-function as the "after" snapshot.
