a685fcdc96 [] go.mod: Use range over int
Since Go 1.22 a "for" statement with a "range" clause is able
to iterate through integer values from zero to an upper limit.

They are not representative, as the worst case is when we have multiple
items of different lengths. However, `FileName` is usually less than 100
in practice, so the asymptotics is the same.

6ace2f597e [] pilorama: Add test for duplicate directory behaviour
When AddByPath() is called concurrently on 2 different nodes,
internal path components may be created twice. This violates some
of our assumptions in GetByPath() and, indirectly, in S3 handling of
GetSubTree() results.

Add a test for the correct behaviour, fixes will follow.

5335e7089e [] pilorama: Speedup TestForest_ApplyRandom()
Some of our pilorama tests fail on CI.
The reasons are not obvious, but one possible improvement
is using `WithNoSync` option for these. It should have much effect,
because we are writing on the tmpfs, but doesn't hurt anyway.

If I replace `t.TempDir()` with a local directory, test execution time
goes down from 5s (sync) to 0.4s (nosync), which is the same time as
with `t.TempDir()`. Maybe we have some strange CI configuration.

```
