Temporal coordinator replay fixtures

vyral-run-coordinator-v1-legacy-completion.json is a completed Vyral.RunCoordinator.v1 history captured with Temporal .NET SDK 1.17.0 from the coordinator shape that existed before Vyral added its continue-as-new patch marker. Its workflow input and activity payload use only synthetic fixture-run data.

Worker, build, and Temporal run identifiers were replaced with fixed fixture values after capture; the event sequence, command attributes, and payloads were not changed. The normal test suite replays this history offline with the current coordinator. Do not regenerate it merely to make an incompatible coordinator change pass: retain the required patch branch or introduce a new workflow type/version. A negative-control replay with an intentionally different command stream proves the fixture would detect nondeterminism rather than passing vacuously.
