chore: register the cordis group across repo gates and docs

Everything outside the package and example that a new top-level group and a
new demo touch: GROUP_ORDER in gen-module-graph and gen-doc-graphs (plus the
tools-service consumers list, the APP_EXAMPLES entry, and the graph-atlas
label/mode rows), the knip e2e entries, the packages/README group row, the
AGENTS.md layout and demo lines, and the regenerated module-graph /
config-catalog / graph-atlas / capability-seams / composition artifacts.
AGENTS.md and examples/AGENTS.md word-budget ceilings rise to current+5%
(1802 / 653): the new group and demo rows are genuine additions to both docs,
not condensable restatements.
