Create Content Brief

GH#657 Framing B — republish wave. Bundle now ships `dependencies: []` in its signed manifest (injected by `publish-skrpt.mjs` for `--shared` publishes), so the App's dep-referenced install pipeline (post-PR #47) accepts it on standalone update via Hub Update-all. No content changes.

GH#651 Hub publish — republish to populate `nodes[].content` in object_manifest for prompt nodes. The /api/shared/<slug>/<v>/metadata endpoint now exposes `nodes[].content` for type='prompt' (GH#650 / GH#651), used by the engine validator's dep-aware loop-body `{{loop.item}}` interpolation check. Pre-fix publish-skrpt.mjs stripped content uniformly; aba4ccd7 preserves it for prompts. No content changes from v1.0.1; signed-bundle data identical, only D1 object_manifest gains the `content` field.

GH#645 Row 3a — republish with `manifest.id` aligned to Hub catalogue UUID. Pre-K-037 v1.0.0 bundle carried a local `manifest.id` that drifted from the catalogue UUID. Row 5 (`0d9c9dbe`) reconciled the source file but not the signed bundle; v1.0.1 ships the corrected `manifest.id` so the batch-of-81 consumer migrations (GH#645 Row 3b) can pin this version and pass engine STEP 4d. No content changes.

Initial catalogue release as independent shared object (GH#612 Wave 3).
