fix(pm): check-clause2-carriers keys the OWED review of record by lane

`needsRecordRead` — C6's population gate, and the sweep's read budget — owed
a record only in the completed state (a cleared `Clause-②: yes`). Under the
lane rule the spec and skills lanes owe the contract review on EVERY round
they deliver, `no` included, and a `no` round hangs no carrier to mark its
review pending: PRs #18530 / #18529 (spec-lane `no` rounds) read 0 here with
no record on either head. The population now adds the `no` rounds of the two
lanes, read off the card's `domain:*` labels (`LANES_OWING_REVIEW`,
`laneOwesReview`; unreadable labels stay UNJUDGED). A `no` elsewhere still
owes nothing. A cleared `yes` outside the two lanes keeps its row and its
exit — the `yes` is a limb hit and limb-hit work is owed — but its remedy is
lane routing (re-lane to spec, or correct a false `yes`), never a
default-tier self-review and never an at-tier subagent from that lane. The
C6-RECORD note prescribes the clear-citation only where a clear exists. New
floored battery, 34 cases; roster floor 32 → 33.
