Add support for KYAML encoding format

[diegolovison]

Standard YAML manifests can lead to silent errors, implicit type coercion bugs (such as unquoted strings like NO being parsed as boolean false), and whitespace parsing inconsistencies across different toolchains.

I would like to have support the KYAML encoding standard (as defined by Kubernetes).

This could include:

• Parsing inputs using KYAML rules
• Validating/linting manifests against the KYAML specification
• Exporting/formatting YAML output into compliant KYAML

Additional context

• Official Kubernetes KYAML Documentation: https://kubernetes.io/docs/reference/encodings/kyaml/
• KYAML provides a strict, unambiguous subset of YAML tailored for Kubernetes workflows, ensuring consistent parsing and preventing common formatting bugs.
