fix(projection): a resurrected row must enter matched to be seen

The previous commit made a stamped slug count as retired, and skipped such rows
before the heuristics. That is right for a genuinely retired row and wrong for a
resurrected one: `stale` is computed from `matched`, so a row that never enters
`matched` is invisible — not retired, so not stale; path-matching its own file,
so never reported. All six kept returning `noop`.

A row whose slug carries the mark while its flag is clear now lands in `matched`
under its own key, which is what makes it stale and therefore retirable. A row
that is actually retired is still skipped outright: nothing to do, nothing to
re-decide.

This is the same mistake as the original path fallback, in the opposite
direction: there a row was matched when it should not have been, here it was not
matched when it had to be.

748 pass.
