Close out INFO-WP-0030; record second Emission Cadence declaration

INFO-WP-0030: register practice-pattern/explicit-unsafe-diagnostic-mode
(adapted from coordination-engine's OrwellLoggingDiagnostics candidate,
INFO-DEC-2026-003) at canon 0.13.0, close the assimilation, and notify
coordination-engine for COORDINATION-WP-0004-T02. Workplan finished.

INFO-WP-0029: record activity-core's source-owned declaration (T03/T04
done) with its expected-rate/calendar-schedule incompatibility as
demand/EmissionExpectedRateCalendar.md, and record audit-core's
structural-only observer evaluation of net-kingdom's declaration as a
steward note. No party has yet produced a real observer result against
traffic, so T05 and the workplan stay blocked on external action.

Updated artifact-count and practice-pattern-count assertions in
tests/test_cli.py and tests/test_service.py for the new artifact.
