close_range: honor last bound and CLOSE_RANGE_CLOEXEC flag
close_range was captured as a single-fd fd_event carrying only first, so
the runtime evicted every tracked fd >= first, ignoring the last upper
bound and the flags. Bounded calls wrongly dropped still-open higher fds,
and CLOSE_RANGE_CLOEXEC (which keeps fds open) was treated as a full close.
Reclassify close_range to the two_fd_event kind, mapping fd_a/fd_b/extra to
first/last/flags. The runtime now closes only the inclusive [first, last]
range (a negative last from ~0U means unbounded) and skips eviction when
CLOSE_RANGE_CLOEXEC is set or the syscall fails.
