[Feature Request] Add graceful deferred exit option to wait for current turn completion

Feature Request
Add a "finish current turn, then exit" option (graceful/deferred exit)

Description:

Currently, "exit" terminates the CLI immediately, even if Claude is mid-task. The only ways to avoid losing in-progress work are:

• Wait for the turn to finish before exiting, or
• Use /background to detach and let it keep running, or
• Ctrl+C to hard-interrupt (which stops the turn early)

There's no way to say "let the current turn complete, then stop" without babysitting the session until it's done.

Requested behavior:

A way to queue an exit that takes effect only after the in-progress turn completes — e.g.:

• /exit --after-turn or a new command like /exit-when-done
• Or: typing "exit" or /exit while a turn is running shows a prompt/status like "Exit queued — will quit after this turn finishes" instead of quitting immediately, with an option to cancel the queued exit.

Why this matters:

For longer-running or multi-step tasks, I want to step away without either (a) manually watching for completion to type /exit at the right moment, or (b) risking a mid-task interruption by exiting too early. /background is a decent workaround for "let it keep running," but doesn't help when the intent is specifically to end the session cleanly once the current work is done.
