fix(#3864): smart-entry classify() matches the verif* status stem (#4052)

* test(#3864): smart-entry classify must match the verif* status stem (failing first)

* fix(#3864): classify() matches the verif* status stem, aligning with normalizeStateStatus

"verified"/"verification" contain no "verify" substring, so the
exact-word branch never matched: a STATE.md declaring status: verified
fell through to situation "unknown" (or idle-stranded on a clean tree
with unpushed commits — differently wrong, which made it look
intermittent). state-document's normalizeStateStatus already matches
any verif* stem; the classifier now uses the same stem, so the two
owners agree on the invariant. verify_failed is tested earlier in
classify(), so failed verification still wins. Negative controls
(completed/executing/planning/paused) unchanged and pinned.

* test(#3864): review fold-in — the real handler-written verification status pinned both ways

'Phase complete — ready for verification' (state-document.cts's own
Status default) carries the verif stem but names completion: at 5/5 it
must stay complete (isComplete beats the stem), mid-project it must
route to verify-pending (pre-fix it fell through to unknown/idle-
stranded — a real behavior change beyond the literal verified repro,
sanctioned by the issue's own verification→verify-pending table).

* chore(#3864): changeset fragment (pr number backfilled after PR creation)

* chore(#3864): backfill changeset PR number (4052)

+smart-entry classifies a STATE.md status of verified (or verification) as verify-pending instead of falling through to unknown — the classifier matched the exact word verify and missed the verif stem its own normalizeStateStatus uses (#3864)
