Registry-aware block preview in the editor

In block mode, registry-resolved runes — collection, relationships, aggregate, xref, expand, and data-bound sandbox — render as unresolved sentinel shells with no explanation. They resolve in core postProcess against coreData.registry, which the client-side block renderer never runs; RUNTIME_ONLY_TYPES in block-renderer.ts only placeholders nav*. The server already holds the registry and resolvers (the full-page iframe preview uses them), so render these blocks server-side; where that's not possible, show an honest placeholder instead of an empty shell.

Acceptance Criteria

  • Blocks containing collection / relationships / aggregate / xref / expand render with real resolved entity data in block mode (server-rendered against the cached registry).
  • Data-bound sandboxes (SPEC-093) receive their data-rf-records payload in block mode so window.RF_DATA previews work.
  • When resolution isn't possible (registry still indexing, resolver error), the block shows a labelled placeholder stating what it is and why it can't render — never a silent empty shell.
  • Resolved block previews refresh when the pipeline cache refreshes (today: on save; live updates arrive with WORK-056).
  • Non-registry blocks keep the current pure client-side render path (no latency regression for ordinary blocks).

Approach

  • Detect registry-dependent runes in a block client-side (tag-name set derived from served rune metadata, not hardcoded — the resolver-backed runes are known to the core config).
  • For those blocks, call the existing POST /api/preview-data (or a lighter POST /api/preview-block) so the server runs the Phase-4 postProcess chain with cachedAggregated + hook sets — the same path renderPreviewContent already uses (packages/editor/src/preview.ts).
  • Extend RUNTIME_ONLY_TYPES handling in app/src/lib/preview/block-renderer.ts into a general "server-resolved" branch with the labelled-placeholder fallback.
  • Invalidate server-rendered block previews on the existing pipeline-cache refresh signal.
