Add ability to inject custom Kubernetes manifests through the
values.yaml file. This allows users to deploy additional
resources (Deployments, Services, ConfigMaps, etc.) without
modifying the chart templates.

The template supports multiple input formats: list of objects,
map of named objects, and raw YAML strings, providing maximum
flexibility for users.

- Create templates/extra-objects.yaml with flexible rendering
- Add extraManifests parameter in values.yaml with documentation
- Support Helm template variables in injected manifests
- Handle list, map, and string YAML formats automatically
