v2.0.0

Scenario synthesis and coverage. playbook coverage splits every walkthrough decision point into its branches (each severity, tier or impact level named, both sides of a KB match or customer-facing condition, and an otherwise branch) and reports which scenarios cover each one and how many scenarios sit on each side of every rubric criterion; procedures with uncovered branches or one-sided criteria are flagged, and --strict makes that a failing exit. playbook synthesize derives one scenario per branch (or per uncovered branch) from the closest hand-written template, inferring expected outcomes from scenarios that share the criterion's condition variables and tagging the rest needs-expert. Both sample sets cover all 11 and 8 branches offline; 31 tests pass, 2 skip by design.
