[Feature Request] Improve rewind functionality or provide alternative undo/state management

Bug Description
rewind is useless to me as a concept, but even disabling it still leaves claude-code broken and awkward

Issue 1:

Title: Rewind prompt shown despite rewind: false in config

Body:
When rewind is set to false in the Claude Code config, abandoning a response still presents the rewind selection prompt, forcing the user to select "current" every time. The setting should suppress
this prompt entirely.

Steps to reproduce:

1. Set rewind: false in config
2. Start a response, then abandon it
3. Observe that the rewind/current selection prompt still appears

Expected: No prompt — just continue with current state.

Issue 2:

Title: Soft-lock after clear + Esc with rewind disabled (2.1.71)

Body:
With rewind: false in config, clearing a session and then pressing Esc causes Claude Code to hang. It appears to try to display rewind history that doesn't exist. The session becomes unresponsive and
requires Ctrl+C to recover.

Steps to reproduce:

1. Set rewind: false in config
2. Start a session (version 2.1.71)
3. Clear the session
4. Press Esc
5. Session is soft-locked — no input accepted

Expected: Esc should either do nothing or behave gracefully when there's no rewind history.
