feat(zora-designer): migrate screenshot analysis to its owning package

[artiphishle]

Problem

@ankhorage/utility/image was intentionally removed by ankhorage/utility#75 because screenshot analysis does not belong in Utility. Devtools still ships the managed zora-designer screenshot analyzer against Utility 0.5.x, so Renovate updates such as #242 cannot move the direct Utility dependency beyond 0.5.x without breaking that capability.

Goal

Move the managed ZORA Designer screenshot-analysis path to the future dedicated owning package once that package and its public API exist. Until then, Devtools must keep its direct @ankhorage/utility dependency below 0.6 rather than recreating the removed Utility API or adding a compatibility shim.

Scope

• identify/use the dedicated owner package for screenshot/image analysis;
• migrate src/tools/skills/assets/zora-designer/scripts/analyze-screen.ts to that released public API;
• update the screen-analysis reference and ZORA Designer routing text;
• move/remove Devtools-local image-engine dependencies according to the new owner contract;
• update deterministic integration tests and managed-skill synchronization coverage;
• remove the temporary Renovate @ankhorage/utility <0.6.0 constraint only after the migration is released;
• then allow the current Utility release through normal Renovate flow.

Do not restore @ankhorage/utility/image, copy its old implementation into Devtools, or add a compatibility facade.

Required skills

Before implementation read AGENTS.md, inspect .agents/skills, and load:

• ankhorage-project-structure
• ankhorage-coding-rules
• hexagonal-architecture

Load the current ZORA Designer/skill-authoring guidance too if present in the repository profile.

Acceptance

• screenshot analysis no longer imports/resolves @ankhorage/utility/image;
• the new owner package is the sole implementation authority;
• no compatibility shim or duplicate image pipeline exists;
• Devtools can upgrade to the current Utility release;
• build, typecheck, lint, Knip, tests, format, docs and changeset validation pass;
• PR is assigned to artiphishle, links this issue, and closes it when complete.
