+fix(runtime): a multi-package artifact's collections are read from `packages[]`, not only from the flattened top level
+
+A release artifact composed with `manifest: 'preserve'` carries every
+definition twice — flattened at its top level, and again under
+`packages[]` (ADR-0130 D4). Only two readers had ever learned the second
+half: `ObjectQLPlugin`'s manifest service and the metadata artifact door.
+Every other reader said `artifact.<collection>` and nothing else, so an
+artifact that carried a collection under `packages[]` alone reached them
+EMPTY — and nothing threw. The app booted clean having lost its
+declarative actions, its scheduled jobs, its seed data, its object routing
+or its default permission set.
+
+`resolveArtifactCollections` — new, and PACKAGE-PRIVATE to
+`@objectstack/runtime` — is now the one way this package reads a top-level
+collection out of an artifact in either shape. It takes the artifact's own
+top-level value first and whole, then adds from each package body — in
+`resolveArtifactPackageOrder`'s dependency order — the items the top level
+did not already claim. A bundle that carries no `packages[]` is returned
+unchanged, by identity: every single-package artifact and every
+`defineStack()` config reads exactly as before. Nothing is added to any
+package's published surface: `@objectstack/core` is untouched by this
+change, and the new module is not named by
+`packages/runtime/src/index.ts`.
+
+Where one collection key is spelled two ways inside one artifact —
+`functions` is `z.union([z.record(…), z.array(…)])`, so two packages can
+each be schema-valid and disagree — the read is REFUSED with an ADR-0112
+envelope (`MIXED_ARTIFACT_COLLECTION_SHAPE`, 422) rather than one spelling
+being skipped. `composeStacks` already refuses the same mix at compose
+time for the same reason.
+
+Taught to use it, in `@objectstack/runtime`:
+
+- `AppPlugin` — declared datasources and their auto-connect, the
+  `datasourceMapping` object routing, the objects handed to the connection
+  service and to the hot-reload seeder, scheduled jobs, seed datasets,
+  translation bundles, and the ADR-0057 security collections
+  (`positions` / `permissions` / `capabilities` / `sharingRules`). A job
+  handler's `ctx.bundle` is now the resolved view too, so
+  `ctx.bundle.objects` answers on a multi-package artifact.
+- `collectBundleActions`, `collectBundleHooks` and
+  `collectBundleFunctionEntries` — including the object-EMBEDDED actions
+  that ride on `objects[]` and disappeared with it.
+- `mergeRuntimeModule` — the declaration half. The sibling ESM module
+  re-supplies every callable regardless of shape, so `functions` was not
+  absent: a function declared `effect: 'writes'` simply came back as a bare
+  callable and defaulted to `'pure'`. It registered, it ran, and its writes
+  were counted as none.
+- `createStandaloneStack`'s surfaced `requires` / `objects` /
+  `permissions` / `positions`, which drive the CLI's tier resolution, its
+  engine and storage-driver auto-registration, and the ADR-0056 D7 default
+  permission set.
+- `resolve-project-database`'s project-database tier, which opens the
+  artifact itself and runs before any stack exists (`os dev`, `os start`,
+  `os db clean`). Without this a multi-package project silently fell
+  through to the unified default database instead of the datasource it
+  declared.
+
+Nothing about what the platform EMITS changes: `composeStacks` and the
+artifact format are untouched, and the flattened top level is still
+written. This is the reader half of the option-B program (#14512).
