Subject: [PATCH] fix: revert broken IME input handling code

Reverts the IME-related changes from v0.0.27-v0.0.29 that broke
Chinese input in terminal TUI apps.

The removed code (isComposing checks, composition event listeners)
conflicted with xterm.js's built-in IME support, causing Chinese
input to fail in TUI applications like Claude Code.

xterm.js already handles IME input correctly out of the box -
no additional handling is needed.
