* fix: stop task renames from wiping task repositories
A title-only PATCH (or WS task.update) converted the absent repositories
field into a non-nil empty slice, which Service.UpdateTask treats as an
explicit replace-with-nothing — deleting every task_repositories row and
dropping the task out of repo-filtered sidebar views. Map "field absent"
to nil at both update handlers so partial updates leave repositories
untouched, while an explicitly empty list still clears them.

* test: assert update-task responses reflect repository state
Address cubic review feedback: make the repo fake stateful so the
explicit-clear test can assert the response body returns no
repositories, and unmarshal the WS payload to confirm the preserved
repository is present, matching the HTTP test's coverage.
