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

1. Create a new project using bun create tui
2. 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)

3. Run with bun run dev
4. 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

[cppsh1t]

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.
