Check full GVK for PodSpec helpers

[AkashKumar7902]

Summary

• match PodSpec helper dispatch on the full request GVK instead of kind only
• reject unsupported group/version/kind combinations with a GVK-specific message
• add regression coverage for argocd.io/v1 Deployment in mutate and extract paths

Fixes #63

Testing

• make test
• make lint
• git diff --check

Pull request overview

Updates PodSpec extraction/mutation helpers to dispatch on full Group/Version/Kind (GVK) instead of kind-only, preventing collisions like argocd.io/v1 Deployment being treated as apps/v1 Deployment (Fixes #63).

Changes:

• Switch PodSpec helper dispatch logic to match full GVK (group + version + kind).
• Improve rejection messaging to reference supported group/version/kind combinations.
• Add regression tests covering mismatched GVKs for both mutate and extract paths.

Please, take a look in the copilot comments. Special the ones about panicking when using nil pointer.

Thanks, I addressed the nil-deref issue now. The PodSpec mutation and extraction paths share the same decoding/target lookup logic, validate the nested spec/template fields before dereferencing them, and return an error for malformed supported objects while keeping the existing rejection response for unsupported GVKs.

I also added regression coverage for missing PodSpec/template paths across the supported resource types.

@AkashKumar7902, please resolve the conflicts.

[AkashKumar7902]

Resolved the conflicts by rebasing the branch onto current main and keeping the full-GVK PodSpec helper changes plus the nil-field guard refactor. Local validation passed with go test ./... and git diff --check.
