* fix(windows): retain native handles whose close is unconfirmed

CloseHandle failure no longer drops the numeric value. A still-open handle
stays owned and can be closed again; a value missing from the handle table
is dropped and never closed again; unreadable liveness blocks another close
until a probe says the value is open.

* test(process): keep scratch until inherited pipes close

Lock the execFileOutput settlement contract: an inherited-pipe descendant
holds the caller's scratch root until it exits, and destroying the readers
is not process-family completion.

* fix(windows): retry admitted file closes before runtime removal

A failed private-file close stays on the runtime that opened it. Runtime
removal closes that same wrapper before the tree walk, including when the
read that opened the file has already returned.

* fix(windows): resume a close after part of the owner is released

A runtime whose directory handle is already released continues with its
parent handles instead of walking that invalid root. A process whose
settlement was already observed retries process close alone, without kill
or poll against the released job.

* test(process): signal only an owned inherited-pipe descendant

Skip the descendant SIGKILL after pipe settlement. On an earlier failure,
signal only when the process command line still contains that test's path.

* fix(windows): do not close a handle again after a failed close

An open liveness probe can observe a reused numeric value. After CloseHandle
fails, drop the value only when the handle table no longer contains it, and
do not call CloseHandle on that number again.

* fix(windows): stop using a close-blocked pipe for I/O

A broken pipe whose CloseHandle fails stays owned, but its numeric value
may have been reused. Later polls and stdin writes treat that pipe as
ended instead of reading or writing the number.
