Prepare the independent plugin/SDK source for Spitzli Cloud release.

• Run own CI exclusively on Blacksmith with pinned setup, actual-region guards and disabled builder fallback.
• Include the reviewed catalog icon, README and screenshot sources where applicable.
• Preserve existing immutable image tags and signed release bytes; source merging does not publish or activate a new runtime.

Validation: exact candidate file hashes checked against the reviewed release inventory; shared Blacksmith workflow/helper tests passed locally. The real Blacksmith check for this dev head is required before merge.

Compute and CMS source fixes need new separately built, signed and admitted runtime versions. No customer activation, credential rotation or production deployment is included.
