SDK 0.34.0 — Package images and videos

Package authors can choose a cover image and attach gallery images or videos in the Godot editor or authoring CLI. Builds retain checked media, GitHub publishing uploads it beside the Manifest and archive, and Catalogue displays it. System covers can provide the default game image in media-capable Rookframe versions.

Media uses Manifest format 2 and requires a Rookframe runtime with format-2 support. Existing format-1 releases remain available. The checker now accepts native PackedStringArray indexing, size and emptiness queries without granting unrelated operations.

Assembled from Rookframe source 07a2b496969cbb9d288359f69c012c77323a1629. Reviewed source and distribution hashes; media, publication and checker regression checks passed.
