…psing - Detect bracketed paste (ESC[200~ / ESC[201~) and dispatch as atomic paste event - Large pastes (>10 lines or >1000 chars) are stored and replaced with a compact marker [paste #N] - Ctrl+O toggles expand/collapse, backspace/delete atomically remove the entire marker - Markers are highlighted with chalk.yellow and expanded back on submit - Follows existing terminal hook patterns (useBracketedPaste alongside useTerminalExtendedKeys) - Array-based chunk buffering to avoid O(n²) string concatenation on multi-chunk pastes - Lazy text cleaning deferred to expand/submit time Known limitation: expand/collapse briefly clears Ink <Static> content above the prompt (React render pipeline constraint). Reference: PR lessweb#45 (closed), inspired by pi project's paste marker approach.

Summary
修复
useTerminalInput中 Bracketed Paste Mode（括号粘贴模式）的粘贴处理代码因未启用而成为死代码的问题，使粘贴多行代码时能够作为原子输入正确处理。Problem
在之前的 commit
4c015a3中，useTerminalInput添加了完整的 Bracketed Paste Mode 处理逻辑：\u001B[200~/\u001B[201~\r\n/\r→\n）paste标志位区分粘贴与按键输入但在实际运行中，Bracketed Paste Mode 从未被启用：
setBracketedPasteMode方法仅暴露在内部 API（useStdinContext）中，公开的useStdin()hook 不包含此方法useTerminalInput从未调用该方法或直接写入 ANSI 转义序列来启用该模式\u001B[200~/\u001B[201~标记因此粘贴多行文本时，终端逐行发送数据，粘贴内容中的
\r字符会被parseTerminalInput误判为 Enter 键，导致粘贴内容被拆解为零散的按键事件，无法正确保留原始格式。Solution
在
useTerminalInput中与setRawMode(true)同级启用 bracketed paste mode，通过直接写入 ANSI 转义序列到 stdout：这与 Ink 内部
App组件的handleSetBracketedPasteMode实现方式完全一致，都是向终端发送\u001B[?2004h（启用）/\u001B[?2004l（关闭）来控制 bracketed paste mode。Changes
src/ui/prompt/useTerminalInput.tsuseEffect中新增process.stdout.write("\u001B[?2004h")和对应的清理逻辑Diff
useEffect(() => { if (!isActive) { return; } setRawMode(true); + // Enable bracketed paste mode so the terminal wraps pasted text in + // \u001B[200~ / \u001B[201~ markers, allowing us to deliver the full + // paste as a single atomic input instead of fragmented key events. + process.stdout.write("\u001B[?2004h"); return () => { setRawMode(false); + process.stdout.write("\u001B[?2004l"); }; }, [isActive, setRawMode]);Effect
Before（Bracketed Paste 未启用）
粘贴
hello\nworld时，终端发送hello\rworld，其中\r被parseTerminalInput识别为key.return = true，粘贴内容被拆分为多个独立事件。After（Bracketed Paste 已启用）
粘贴
hello\nworld时，终端发送包裹后的完整内容：useTerminalInput累加起止标记之间的全部文本，归一化行尾符后作为一次原子操作交付给PromptInput.tsx，key.return = false，所有其他按键标志也为false，仅paste = true。效果对比
\r被误判为 Enterkey.tab = false）PromptInput.tsx归一化Verification
Notes
setBracketedPasteMode仅通过内部useStdinContext暴露，不在公开 APIuseStdin中。由于本项目使用自定义的useTerminalInput（直接监听stdin.on("data")而非 Ink 的useInput/usePaste），直接写入 ANSI 转义序列是最简洁且与 Ink 内部行为一致的方案。paste标志位在InputKey中已就绪，可供后续需要区分粘贴与普通输入的场景使用。
