[PATCH RFC 01/11] sequencer: optionally skip printing commit summary

[Patrick Steinhardt <ps@pks.im>]

When picking commits by using for example git-cherry-pick(1) we end up
printing a commit summary that gives the reader information around what
exactly we have been picking:

```
$ git cherry-pick main
[other 76c8456] bar
 Date: Tue Aug 19 08:07:26 2025 +0200
 1 file changed, 1 insertion(+)
 create mode 100644 bar
```

While useful for some commands, we're about to introduce a new command
where this output will be less so. But right now there is no way to
disable printing this commit summary.

Introduce a new `skip_commit_summary` replay option that does so.
Persist the option into the sequencer configuration so that it persists
across different processes, e.g. when we need to stop due to a merge
conflict.
