When you use e.g. `git switch` to check out a conflicted commit, you're going to end up with the `.jjconflicts-*` directories in your working copy. It's probably not obvious what those mean. This patch adds a README file to the root tree to try to explain to users what's going on and how to recover. The authoritative information about conflicts is stored in the `jj:trees` commit header. The contents of conflicted commits is only used for preventing GC. We can therefore add contents to the tree without much consequence.

New conflicts appeared in these commits:

|
|
To resolve the conflicts, start by updating to it:
|
|
jj new kmkuslswpqwq
|
|
Then use `jj resolve`, or edit the conflict markers in the file directly.
|
|
Once the conflicts are resolved, you may want inspect the result with `jj diff`.
|
|
Then run `jj squash` to move the resolution into the conflicted commit.
