harness: a new PM run reads current launch state and open tasks before each turn, and old messages show their age, row 109 (#1603)

The broker gains a read-only state verb (launch state with the event that set it, open tasks capped). The runner fetches it before each turn and puts a "Current state" block at the top of the request; a failed read fails the turn. turnRequest() adds the message time. roles/pm.md gets one rule: the block is the truth for launch state and task status. Seat session, seat sandbox and cli launcher tests re-anchored to the new request shape.

Built by Researcher, packet 875c515e9. Filbert approved round 3, comment 28333, candidate manifest 0a62225e (11 paths). Sage gate on 9774d70db plus row109.patch: every package node suite and every scripts/test-*.sh green on the first run, skipped 0 in bus, harness and seat. Vikunja #259.
