Add docs/ecosystem-boundaries.md: per-repo boundary table, overlap
hotspots and resolutions (control-plane/scope/resolver vs
feature-control, vocabulary vs info-tech-canon, connectors vs
repo-scoping, ownership vs domain-tree, schema/federation vs
reuse-surface), and concrete reuse actions mapped to the blueprint
roadmap.
Tighten .claude/rules/repo-boundary.md to name all five sister repos
with their consume/reuse/reference/link relationships and scope
config-atlas to its novel core.
