Extends ADR 0075. Surfaced fixing builder's hand-faked package-registry
binding tonight: gitea's manifest declares the provision once with a single
npm-path, conflating what should be independently assignable per ecosystem
(npm/cargo/docker/...) the same way artifact-store and package-registry
were themselves split. Cited in 22-the-work-ahead.md's Phase 2, where the
target state this decision points at was already described a week ago.
Numbered 109, not 108: route-proxy's policy feature (mesh-controller PR
#58, merged today) already cites 'novox/hq ADR 0108' six times for its own
still-unwritten decision record — reserved but never committed. Renumbered
around it rather than colliding.
