Post-yield now also reaps init-adopted (`ppid==1`) tractor procs
that appeared during the test — leaked subactors whose mid-tier
parent died during cascade teardown, reparenting them to init.
Pre-yield snapshot of existing orphans scopes reap to THIS test's
leaks only, avoiding reap of unrelated tractor uses (piker, etc.)
on the box.

(cherry picked from commit 01ce2857ea)
(factored: also default `find_orphans(repo_root=None)` -> cwd so the new bare call sites work ahead of the later intrinsic-identity rewrite)
