Control-plane half of the scheduled-step primitive (ADR 0053). Adds a minimal 5-field cron validator; the manifest parser accepts schedule: "<cron>" on a container, refuses a malformed cron, a non-string, and the pair run-once+schedule. The resolver carries the field through untouched (as run-once is). 4 new tests; full suite green (353 tests, vet clean). Proven end-to-end alongside the host half in mesh-lab assigned-schedule-tick (SUITE_EXIT=0).

catalogue: carry and validate a container schedule (ADR 0053) 78b8b6e256

A container may declare schedule: "<cron>", the recurring twin of
run-once. The resolver already carries a resource's keys through
untouched, so schedule reaches the rendered host declaration on its own;
what belongs here is refusing, near its author, what the host would
otherwise refuse far away.

The manifest parser refuses a schedule that is not a string, one that is
not a well-formed five-field cron (cron.go: fields, ranges, *, comma,
dash, slash), and the contradictory pair run-once + schedule -- a
container runs once and gates, or on a cadence, or stays up, never two.
