* fix(javascript): transient Windows private-runtime source-transfer Parent source-transfer into the Windows private runtime root failed with EPERM on path-based exclusive create. Write through a native transient private-runtime path that closes the handle after flush so per-job rm still works, and yield around the sync write so abort deadlines can fire. * fix(javascript): yield timer phase before Windows source-transfer write
