As a developer I would like to make my plugin available as dynamic plugin and oci

• What: ship as RHDH dynamic plugin and an OCI artifact; document installation.

• Where:

• FE build: plugins/cost-management/package.json (build outputs)

• Packaging scripts: scripts/build-dynamic-plugin.sh, Containerfile/Dockerfile

• Metadata: plugin-manifest.json as required by RHDH dynamic plugin format

• Notes: versioning, SBOM, signatures if required.
