feat: migrate live inventory to five-facet 0.3 and close WP-0006

All seven data/resources records now carry description, decision,
reef/secret refs, and potential vs actual consumers. Discovered
resources use decision.status: gap. Validators require live inventory
to be 0.3. WP-0006 T03 done; workplan finished.
