[Feature Request] Make AskUserQuestion timeout configurable

Bug Description

Title: Make AskUserQuestion timeout configurable (or restore indefinite wait)

Body:

After a recent update, the AskUserQuestion tool now waits ~60 seconds and then continues without my answer, proceeding with empty/unintended selections. Previously it waited indefinitely until I responded.

This breaks my workflow: I'm often reading code, switching windows, or thinking about the answer when the question expires, and then the agent moves on with the wrong assumption — sometimes taking actions I didn't approve.

Request: Please add a setting to configure or disable this timeout, e.g.:

{
"askUserQuestion": { "timeout": 0 }
}

where 0/null = wait indefinitely (the old behavior). Even a global "never time out interactive questions" toggle would be enough.

Related prior request: issue #30740 (closed as "not planned"). Reopening consideration would be appreciated — the 60s timeout causing unintended actions is a correctness/safety issue, not just a convenience one.
