"Revert message" should not modify code

[iAvoe]

Description

In a conversation, the "revert message" is actually reverting code, which is not said clearly or prompted with a warning. This is still okay since the user can revert the revert feature, until I accidentally clicked revert on an old conversation, which somehow broke my Git, resulting several files missing despite executing Git hard reset.

Currently I just learned to never use revert anymore to prevent damages like this, which is also not ideal.

There are several fixes may be applied:

• Prompt user with warning that revert conversation actually reverts code
• Separate "revert message" with "revert changes" (user can choose only revert conversation without reverting code)
• Remove "revert changes" entirely, since some changes are still good and can be carried to another conversation session

Plugins

None were used

OpenCode version

1.16.2

Steps to reproduce

1. Go to a project that has multiple git commits with many session conversations
2. Go to a rather old conversation
3. In the old conversation, scroll up to an early dialog with file changes
4. Click "Revert message", which messes your project up even with Git commits, mostly are deleted files

This issue might be a duplicate of existing issues. Please check:

• Reverting doesn't actually revert the changes #29005: "Reverting doesn't actually revert the changes" — similar concern about revert behavior
• /undo command only rolls back AI conversation message, not the associated file changes #5474: /undo command only rolls back conversation, not file changes — closely related undo/revert behavior
• /undo only the conversation will be rolled back, but the files will not. #29520 and /undo only rolls back conversation, not file changes — Windows OpenCode Desktop v1.15.11 #29522: Similar reports of undo/revert not affecting file changes as expected

If you believe this was flagged incorrectly, please let a maintainer know.

Well, this seems to be another bug, I arrived at the new issue page via OpenCode's report link, which didn't have a template selection or showing any guidelines. I'll try fix my formatting.

Thank you for updating the issue! It now includes all the required information — a clear description of the problem, steps to reproduce, and your OpenCode version. The needs:compliance label has been removed. We appreciate you taking the time to fill this out properly.

The flags are not duplicated. Revert message and Revert code are not the same thing. I can see some people expected code reverting, but that is more of a feature request. What am I reporting is an UX bug to be mostly specific.
