* Armable DataStore wrapper that can inject faults deterministically.

* Modes:

* - [Mode.Normal]: delegates normally.

* - [Mode.FailBeforeCommit]: throws [exception] before delegating, then resets to Normal.

* - [Mode.FailAfterCommit]: delegates first (durably commits), then throws [exception], then resets to Normal.

* - [Mode.CancelAfterCommit]: delegates first, then cancels the supplied caller job and resets to Normal.

* Each fault fires once; subsequent edits succeed normally. This avoids fragile edit-count assumptions.
