First step of the scheduled-task context's hexagonal migration: the inner-ring model, with zero infrastructure dependencies. - ScheduleSpec / SchedulePolicy value objects - ScheduledTask aggregate root - ScheduledRun aggregate - 9 domain errors, 5 enums Rules are migrated verbatim from their current homes, each method's docstring citing the source line: timezone/cron/next-run calculation from deerflow/scheduler/schedules.py, context-mode and re-arm rules from routers/scheduled_tasks.py, and the four status-derivation rules from app/scheduler/service.py. Two things previously held by convention are now enforced by construction. Validation and normalization live in __post_init__, so building a ScheduleSpec field-by-field cannot bypass them. The skipped tombstone is a separate factory, so it can never be written as the transient queued row that would collide with uq_scheduled_task_run_active. The domain does not serialize itself: mapping the stored schedule_spec JSON in and out stays with the adapter layer, keeping Mapping[str, Any] out of every domain signature. Production code still runs through app/scheduler/service.py -- this commit adds no call sites and changes no behavior.
