Reworks the LCM, reactions, session manager, reaper, and boot wiring onto
the redesigned domain model — collapsing the runtime axis to is_alive,
moving PR facts to the pr table (read back as PRFacts), replacing the
free-form SessionReason with a typed terminal-only TerminationReason, and
dropping Revision/EventType/durable reaction-trackers (CDC is trigger-driven,
escalation budgets are in-memory).
- ports: SessionStore + PRWriter interfaces; PRObservation/RuntimeFacts/
ActivitySignal DTOs; drop LifecycleStore/EventType/ReactionStore.
- lifecycle: single-writer reducer over is_alive; ApplyPRObservation writes
the pr tables and reacts; CI-fix-loop brake derived from pr_checks history;
review comments injected into the agent regardless of author (no bot
detection); merge auto-terminates with pr_merged.
- session: store-assigned "{project}-{n}" ids; folded metadata; status
derived from PRFacts on read.
- reaper: reports the four-valued probe vocabulary unchanged.
- boot: trigger -> poller -> broadcaster; storeAdapter bridges *sqlite.Store.
Lane shrinks 6218 -> 2803 LOC. go build/vet/test -race green.
