Patch Changes

• d175de9: Fix declaration generation for exported machine.provide({ actions }) variants and createStateConfig() fragments with invoke input mappers.

  Entry and exit functions now receive a working enq regardless of their parameter count, including default/rest parameters and forwarding wrappers. Returned context and child patches are applied consistently. Functions that enqueue no effects no longer add placeholder effects to pure transition results.

  import { createMachine } from 'xstate';
  
  const machine = createMachine({
    initial: 'loading',
    states: {
      loading: {
        entry: (...[, enq]) => enq.raise({ type: 'ready' }),
        on: { ready: { target: 'ready' } }
      },
      ready: {}
    }
  });

• 32487c8: Fix nested and parallel state value inference for machines declaring setup({ states }) when exactOptionalPropertyTypes is enabled. Both forms of snapshot.matches(...) now accept valid nested states:

  snapshot.matches({ b: 'x' });
  snapshot.matches('b.x');
