[Bug]: CLI 终端思考时预输入粘贴内容，Pasted Text 占位符无法展开

[ji-tz]

Version line

v2 — Go rewrite (1.x), main-v2 (active development)

Exact version

npm-v1.10.0-rc.1

What happened?

CLI 终端中，在模型思考/推理时向输入框预输入（粘贴）多行内容，
粘贴的内容会被折叠为 [Pasted Text #10 · 41 Lines] 占位符标签。
思考完成后，该标签未被展开，而是原封不动地发出去了。

期望行为
思考完成后，[Pasted Text #10 · 41 Lines] 标签应该被展开为实际的粘贴内容再发出。

Steps to reproduce

1. 发送一条需要较长时间思考的消息给模型
2. 模型开始思考后，在输入框粘贴一段多行文本
3. 粘贴内容被折叠为 [Pasted Text feat(index): config-driven excludes + .gitignore + dashboard UI #10 · 41 Lines] 标签
4. 按 Enter 发送（或等待自动输入）
5. 等待模型思考完成，[Pasted Text feat(index): config-driven excludes + .gitignore + dashboard UI #10 · 41 Lines]自动发送
6. 实际发出的是 [Pasted Text feat(index): config-driven excludes + .gitignore + dashboard UI #10 · 41 Lines] 文字本身，不是粘贴的原始内容

OS / platform

Fixed by #5426 and merged in commit 0b12cf4.

The TUI now expands folded [Pasted text #N · M lines] placeholders before storing feedback in the running-turn interject queue, so when the current reasoning turn finishes the queued message sends the original pasted content instead of the placeholder label.

Release availability: this fix is merged into main-v2, but it is not included in the current published v1.12.0 CLI/Desktop releases. Users will need the next release, or a build from current main-v2, for the fix to take effect.

Verified with:

• go test ./internal/cli -run "Test(QueuedFoldedPasteExpandsBeforeInterjectSend|QueueNewMessageOnEnterDuringRunning|PasteFoldExpandOnSubmit)"
• go test ./internal/cli
• GitHub CI, including cache-impact, lint, govulncheck, coverage, race, desktop, CodeQL, and tests on Ubuntu, macOS, and Windows.
