upgrade: state-machine package upgrade for Solid 2.0

[davedbase]

Upgrades @solid-primitives/state-machine to Solid 2.0 beta.13. The core implementation was redesigned to handle the new async signal batching model: transitions called from within state callbacks are now resolved synchronously via an internal while loop (no signal writes during memo execution), while external transitions via state.to.*() are batched and require flush() before reading updated state in imperative code.

Breaking changes: solid-js@^2.0.0-beta.13 peer dependency required. After calling state.to.*() outside a reactive context, call flush() from solid-js to read the new state synchronously.

Summary by CodeRabbit

• Breaking Changes

  • Updated to require Solid.js v2.0-beta.13
  • State transitions are now batched asynchronously; call flush() after transitions to synchronously observe state changes in tests or imperative code
  • Initialization-time state callbacks now require flush() before reading resulting state

• Documentation

  • Enhanced README with updated timing semantics and lifecycle examples
