feat: scheduled chats are experimental / default-off in v1

Browse source 
Per the v1 scope decision: ship a correct single-process, autonomous core; defer HITL
resume of scheduled runs and clustered operation behind the flag as fast-follows.

getLimits now resolves to disabled unless an admin explicitly opts in via
interface.schedules (true, or an object without use:false). Absence/null/false all mean
off, so a deployment that never opts in never runs the scheduler. initializeScheduleEngine
refuses to arm when the base config leaves it disabled, so "off" means the engine is not
running at all (no tick, no claims) rather than running and refusing at dispatch.

The per-principal availability and the base-only global kill switch are unchanged; this
only flips the default and gates engine startup.
