The RoutineRunner and RoutineScheduler were written against a different
interface than what RoutineStore actually implements, causing TypeError
crashes as soon as any routine became due. This adds the missing
agentId/catchUpLimit fields to the Routine type and DB schema, adds
startRoutineExecution/completeRoutineExecution/cancelRoutineExecution
methods to RoutineStore, and fixes all property name mismatches
(lastExecutedAt→lastRunAt, trigger.cron→trigger.cronExpression,
policy value alignment) in the runner, scheduler, and tests.
