docs(pm): a cross-seat ask of any kind is work — it lands as a card, the wait flips pm:blocked at it (#9852)

Scope clarification on the 跨座位转移 clause: cross-seat asks (a reading, an
obligation to open cards, an access/authorization need) are work and land as a
card in the target lane's queue with a provenance line and a one-line
executable criterion; a seat-post knock or ruling comment is never the only
carrier — comments are accelerators, not records, and prose is invisible to
every candidate query, sweep and age alarm. The waiting card flips pm:blocked
+ Blocked-by: at the request card in the same stroke, so the existing unlock
scan, candidate queries and aging machinery cover both ends — no new labels,
no new sweep. When the target repo is unreachable the request card lands in
objectstack via the seam-card rule (repo:* + named reader), which also
dissolves the requester-has-no-access failure.
