feat(freestyle): soft-lock steering preemption (Slice 5)

- DecisionKind gains PREEMPT; DecisionJournalState tracks planLocked. - DefaultDecisionJournalReducer: ExecutionPlanLockedEvent flips planLocked (no record); post-lock steering notes recorded as PREEMPT with a 'PRIORITY DIRECTIVE' summary, pre-lock stay STEERING. - SessionOrchestrator.buildSteeringNoteEntries: post-lock notes surfaced as pinned L0/SYSTEM 'PRIORITY DIRECTIVE' entries ahead of the plan; pre-lock keep L2. Graph re-routing intentionally deferred (priority surfacing only). - Tests: PreemptSteeringJournalTest, SteeringPreemptionTest.
