docs(adr): ADR-0130 — the release artifact is the co-ownership boundary (one artifact, N packages) (#14151)

Records the decision chartered on #14144 (epic #14122): compile per package,
ship one JSON, keep N manifests inside it, register N packages in dependency
topological order at load time.

Status: Proposed — governed surface, awaiting the maintainer's hand-merge.

Part of #14122
