fix(#4020): bound the test run's temp footprint with a swept run-scoped root (#4207)

Browse Source 
* test(#4020): the runner must bound and sweep a run-scoped temp root

* fix(#4020): bound the run's temp footprint with a swept run-scoped root

* test(#4020): isolate the env-mutating rows in child processes

* fix(#4020): gate root removal on ownership so nested runners spare the outer root

* test(#4020): pass the probe file via --files, the runner's explicit-file flag

* test(#4020): resolve the probe by basename, as --files matching requires

* test(#4020): assert root survival, not content survival, in the nested-row

* chore(#4020): changeset for the run-scoped temp root

* chore(#4020): backfill changeset pr number

* fix(#4020): the sweep spares ancestors of the runner's own selected files

* fix(#4020): TMPDIR precedence — an operator redirect beats inherited TEMP/TMP

* fix(#4020): only the root's owner sweeps — a nested runner spares live sibling fixtures
