SDK 0.9.2 — Shared Package resources

Packages have no OS dependency or target. The SDK now produces one shared artifacts/package.pck containing the Implementation, all declared Presentations and resources. The OS target CLI option is removed.

Texture alternatives are included automatically while preserving authored import settings. The checker inspects every alternative and retains Godot's native-format and software-decompression fallback. Device variation remains phone/tablet/desktop Presentations with the documented fallback.

This kit is assembled from Rookframe commit c29c13a9a285ccde5b2e9029b849a8424595d309 and pins UI Kit commit 9de97beeede7f9d803e6ea0abef67730cdc84692. Current Rookframe builds include the matching portability fix; existing immutable releases such as Calendar v0.9.0 work unchanged.

Validation: the complete Rookframe Fast Gate passed in 83.236 seconds (400 C# tests, 77 tool tests and native Godot checks), and the distributed file inventory was verified.
