claude-code - 💡(How to fix) Fix [FEATURE] Support non-blocking concurrent interaction within a single session

Preflight Checklist

• I have searched existing requests and this feature hasn't been requested yet
• This is a single feature request (not multiple features)

Problem Statement

当前会话是串行的，任务执行期间无法插入新问题。希望能支持后台任务执行 + 会话内非阻塞提问，让用户在等待长任务时可以继续交互 比如让 Claude 跑测试，同时问一个代码逻辑问题，不用等测试跑完

Proposed Solution

1. Background execution — When a user prefixes a prompt with /bg (or Claude detects a long-running task), the task runs in the background. The user gets back the prompt immediately and can continue asking questions in the same session.
2. Shared context — Background tasks and the foreground conversation share the same session context. Results from background tasks are appended to context when they complete, not blocked on.
3. Status bar / notification — Show running background tasks in a status line (e.g., ⧖ 2 tasks running). When a background task finishes, surface a brief notification so the user knows to check results.
4. Result retrieval — New command /tasks to list background tasks and their status; /tasks <id> to pull completed results into the conversation.
