refactor(calendar): move the reminder source beside the feeds

CalendarWatch, the client resolution, and the slot policy were all
feed domain living in the claw's config and source tree; only the
extension adapter was the claw's. The reminder source now ships in
the integration as the default answer to "what does a start time
mean": one slot per lead time, calendar:<name> keys, fed to the
consumer's dispatcher. The crate doc drops its no-policy claim to
match, and the claw's resident prefixes take the calendar prefix
from the integration so the spelling cannot drift.
