[Feature Request] Add "Ask about it" option to permission prompts for clarification without rejection

Bug Description
Feature request: a fourth "ask about it" option in the permission prompt

The permission prompt currently offers: allow / allow and don't ask again /
reject (with optional free-text feedback). There is no way to ask a question
about the proposed action while keeping it pending.

Today, wanting to say "sure, if this really only reads the file" means picking
reject. Claude then has to re-propose the identical command and the user has to
approve it in a second dialog — two extra round trips for what was a
clarification, not a refusal.

Requested: a fourth option, e.g. "Ask about it", that sends free text to Claude
and keeps the tool call pending. Claude answers, and the same prompt returns
with allow/reject still available. Typical uses:

• "yes, if it only lists the directory and writes nothing"
• "what does the -a flag do here?"
• "why this path and not the config file?"

Impact: users learning to trust an agent need to ask before approving. Making
questions cost a rejection pushes them toward blind approval or toward Esc,
which aborts the whole turn.
