What Jj Squash does

Squash the current change into its parent.

**Show what will be squashed:**

jj log -r '@ | @-' --no-graph -T 'change_id.shortest(8) ++ " " ++ description.first_line() ++ "\n"'

**Squash:**
```
jj squash
```
This moves all changes from `@` into `@-` (parent). The working copy becomes a new empty change on top.
**If the squashed change had a bookmark, it might need moving:** Check if the old `@` had a bookmark that should now be on the parent.
