Adds autocannon as a devDependency for the load-test tooling (T001), and the shared schema migration T002 blocks: SLARun.version for optimistic concurrency, plus two Postgres partial unique indexes (assignments_one_current_per_ticket, escalation_events_ticket_rule_unique) guarding against the assignment and escalation races research.md documents. Applied directly to both the real dev DB and the throwaway test DB. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
