Claude f6969e538b fix(io): deregister a stopped actor's fd wait on the unwind path ...

A stopped actor unwinding out of wait_fd's park leaked its waiters entry
and the kernel-side EPOLLONESHOT registration; the stale entry then failed
every future wait_*() on that fd with AlreadyExists (the defensive bare DEL
in epoll_register sits behind the contains_key check, so it never ran).

Fix where the invariant breaks: a drop guard in wait_fd, armed after a
successful register and forgotten on the normal wake (where FdReady already
removed + DEL'd). On unwind it cleans up iff the entry is still this wait's
(pid, epoch) — an entry consumed by a racing FdReady means the fd may carry
another actor's fresh registration, which must be left alone. Closes the
v0.2 fd-hygiene TODO.
