Issue Title

Bug: useKeyboard hook not responding and createSignal updates not reflecting on Windows (MINGW64/Git Bash)

Issue Body

Description

I copied a simple counter example from the official OpenTUI Solid documentation. The example uses useKeyboard to handle key presses (Up/Down arrows for counting, ESC to exit) and createSignal for state management. However, neither the keyboard events nor the signal updates are working on Windows when running with Bun in a Git Bash (MINGW64) terminal.

Reproduction Steps

Create a new project using bun create tui
Copy the following code into src/index.tsx (exactly as shown in the docs):

import { render, useKeyboard } from "@opentui/solid"
import { createSignal } from "solid-js"

const App = () => {
  const [count, setCount] = createSignal(0)

  useKeyboard((key) => {
    if (key.name === "up") setCount((c) => c + 1)
    if (key.name === "down") setCount((c) => c - 1)
    if (key.name === "escape") process.exit(0)
  })

  return (
    <box border padding={2}>
      <text>Count: {count()}</text>
      <text fg="#888">Up/Down to change, ESC to exit</text>
    </box>
  )
}

render(App)

Run with bun run dev
Try pressing Up/Down arrow keys or ESC

Expected Behavior

Pressing Up arrow should increment the counter (display updates)
Pressing Down arrow should decrement the counter (display updates)
Pressing ESC should exit the application

Actual Behavior

The counter remains at 0 and does not update
The keyboard event handler inside useKeyboard callback is never called (verified by adding console.log)
ESC does not exit the application
The UI renders correctly but is completely unresponsive to keyboard input

Environment

OS and Terminal:

OS: Windows 10 (Build 19045)
Shell: MINGW64_NT-10.0-19045 (Git Bash for Windows)
Terminal: Git Bash terminal

Runtime and Package Versions:

Node.js: v22.19.0
Bun: 1.3.6
TypeScript: ^5
@opentui/core: 0.1.81
@opentui/solid: 0.1.81
solid-js: 1.9.9

I first discovered the useKeyboard issue while testing logs in another project that uses opentui. Later I switched to using useRenderer().keyInput.on("keypress", callback) directly and that successfully triggered events. I then discovered that signals were also not working properly, so I finally copied the simplest counter example to test and found it still doesn't work.
