Description

jj should have a command to sync all of my branches (or some subset) with a remote via merge or rebase, in a single operation.

Since that could cause a lot of big changes at once, it'd be nice to show a preview of changes that will be performed and prompt to confirm and/or output a very clear summary of what all changed from that sync operation.

Contributor guide

Research direction
Examine the existing `jj git` subcommands (e.g., fetch, push) in the source code under `src/commands/` to understand the pattern for implementing a new command. Study how jj handles remote branches and rebase/merge operations. Review the issue comments for design discussions and any specific requirements. Note that this issue has an assignee, so coordinate with them before starting work.
