* 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
