feat: switch to the modelpack model-spec

[chlins]

This pull request updates the codebase to use the new github.com/modelpack/model-spec/specs-go/v1 import path instead of the deprecated github.com/dragonflyoss/model-spec/specs-go/v1, and updates related code references accordingly. It also updates a constant annotation key to reflect the correct organization.

Closes #317

Dependency and import updates:

• Replaced all imports of github.com/dragonflyoss/model-spec/specs-go/v1 with github.com/modelpack/model-spec/specs-go/v1 throughout the codebase and tests to use the new canonical model spec package. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Code and constant updates:

• Updated all references to legacymodelspec types and constants in pkg/backend/attach.go to use modelspec equivalents, ensuring consistency with the new import. [1] [2] [3]
• Changed the value of the annotationModelfile constant from "org.cnai.modctl.modelfile" to "org.cncf.modctl.modelfile" in pkg/backend/build.go to reflect the correct organization namespace.

Summary of Changes

Hello @chlins, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request performs a significant dependency migration, moving the project's reliance from a deprecated model-spec package to its new, canonical location under the modelpack organization. This change ensures the project utilizes the most current and officially supported model specification, enhancing maintainability and future compatibility. Additionally, an organizational annotation key has been corrected to align with the updated branding.

Highlights

• Model Spec Migration: The codebase has been updated to use the new github.com/modelpack/model-spec/specs-go/v1 import path, replacing the deprecated github.com/dragonflyoss/model-spec/specs-go/v1 across all relevant files and tests.
• Annotation Key Update: The annotationModelfile constant in pkg/backend/build.go has been changed from "org.cnai.modctl.modelfile" to "org.cncf.modctl.modelfile" to reflect the correct organizational namespace.

Code Review

This pull request correctly updates the import paths from github.com/dragonflyoss/model-spec/specs-go/v1 to github.com/modelpack/model-spec/specs-go/v1 and updates the annotation key as described. The changes are mostly mechanical but well-executed. I've identified one area in pkg/backend/attach.go where the code can be refactored to improve maintainability by reducing duplication. My suggestion is to adopt a more data-driven approach for selecting processors.
