Adds the 2026-06-26 decisive finding: the bridge forwards `xworkmate.*` method
names the OpenClaw 2026.6.2 gateway does not implement (it uses native
tasks.get/list/cancel and artifacts.list/get/download). Documents the corrected
end-to-end turn timeline with the three break points (tasks.get unknown method;
{taskId}-only param shape + taskId!=runId; artifacts.* drift blocking .md delivery),
the evidence (gateway source + schema + CHANGELOG), the implemented task-lifecycle
fix, and the precisely-specified remaining work (artifact-method alignment + test
fixture migration). Corrects the earlier (wrong) "push/pull mismatch" conclusion.
