Phase 921: export mesh validate alignment extract + diagnostics inputs extract + validate coverage facade (v0.8.888)

Non-breaking refactor only — validate-alignment module centralizes alignment orchestration; validateExportMeshFetchRegistryCoverageFromScope facade deduplicates coverage calls; buildExportMeshFetchRegistryDiagnosticsInputsFromScope extracts diagnostics input builder; validate becomes thin re-export. CI: test:ci-phase921 with live audit archive RPC.
