[Bug] Ctrl+G with micro editor erases input text on exit

Bug Description
Bug: Ctrl+G with micro editor erases all input text

Environment:

• macOS
• Editor: micro
• Terminal: [твой терминал, например iTerm2/Terminal.app/Wezterm]

Steps to reproduce:

1. Start typing a prompt in Claude Code
2. Press Ctrl+G to open external editor (micro)
3. Make edits or just save without changes
4. Exit micro (Ctrl+Q)

Expected: Edited text returns to Claude Code input
Actual: All previously typed text is erased, input buffer is empty

This makes Ctrl+G unusable with micro editor. Related to issues #11286, #16460.

• Terminal: WezTerm
