F1: add a test that empties a non-empty doc via a change-origin transaction
(ySyncPluginKey meta, the shape y-tiptap sets for remote/merge updates) and
asserts the intentional-clear signal is NOT emitted — pinning the
isChangeOrigin early-return that keeps remote emptiness from punching through
the #248 server guard. The 4 existing tests use local transactions and never
exercised that true-path (verified: removing the guard fails only this test).
F2: record the #248 empty-overwrite guard and the #251 intentional-clear in the
CHANGELOG [Unreleased] Fixed section.
