Unhandled Promise Rejection: Bad substitution: chunks[1].startOffset

從呼叫 shell-quote 的命令解析路徑開始，接著檢查堆疊追蹤中的 parse.js 位置，以及周圍的 promise 錯誤處理。找出一個會觸發替換失敗的輸入，並驗證該命令要麼能夠執行，要麼產生一個已處理且清楚的驗證錯誤，而不是未處理的拒絕。

Summary

Command Code crashes with an unhandled promise rejection when parsing a shell command.

Environment:

• OS: Ubuntu Linux
• Node.js: v22.20.0
• Command Code: latest installed version
• Shell: [bash/zsh/etc.]

Error:
CRITICAL: Unhandled Promise Rejection!
This is an unexpected error. Please file a bug report.

Trace ID:

The error appears to originate while parsing the shell command/environment
variable substitution through the shell-quote dependency.

Expected Behavior

The command should either execute normally or return a handled/clear
validation error rather than crashing with an unhandled promise rejection.

Actual Behavior

The command should either execute normally.
