[DOCS] Rewind command docs omit `/undo` alias

/rewind command entry and related rewind/checkpointing guidance

Current Documentation

The command reference currently documents only one alias for /rewind:

| /rewind | Rewind the conversation and/or code to a previous point, or summarize from a selected message. See checkpointing. Alias: /checkpoint |

Related pages also consistently tell users to use /rewind, without mentioning /undo as an equivalent command:

Press Esc twice (Esc + Esc) or use the /rewind command to open the rewind menu.

* Esc + Esc or /rewind: press Esc twice or run /rewind to open the rewind menu and restore previous conversation and code state, or summarize from a selected message.

* Course-correct early: If Claude starts heading the wrong direction, press Escape to stop immediately. Use /rewind or double-tap Escape to restore conversation and code to a previous checkpoint.

What's Wrong or Missing?

Changelog v2.1.108 says:

/undo is now an alias for /rewind

But the current docs still present /rewind as the only documented command name, aside from the older /checkpoint alias.

That leaves the documentation outdated after v2.1.108:

A. The command reference is incomplete

Users reading commands cannot discover that /undo is a supported alias for /rewind.

B. Rewind-related workflow pages are now misleadingly narrow

Pages that instruct users to run /rewind do not mention that /undo works the same way, so users who encounter /undo in release notes, transcripts, or team instructions have no documentation confirming it is valid.

Suggested Improvement

Update the rewind/checkpointing docs to reflect the v2.1.108 alias addition.

Minimum fix:

1. In commands, update the /rewind row to mention both aliases, for example: Alias: /checkpoint, /undo.
2. In checkpointing, add a short note near the first /rewind instruction that /undo is an alias and opens the same rewind menu.
3. In user workflow pages that currently say only /rewind, add a brief alias note or update the wording to /rewind (alias: /undo).

Impact

Medium - Makes feature difficult to understand
