📝 Walkthrough

Walkthrough

The build now validates OLM v1 bundles, constructs file-based catalogs with OPM v1.72.0, rejects deprecated catalog images, updates bundle metadata and labels, and ignores generated catalog artifacts.

Changes

OLM v1 build and catalog migration

Layer / File(s)	Summary
Bundle v1 validation and labeling Makefile, Containerfile.plugin, bundle/bundle.Dockerfile	Bundle construction and targets now use OLM v1 labels and paths, validate the bundle schema and media type, use OPM v1.72.0, and disable app registry delivery.
File-based catalog build Makefile, .gitignore	Catalog generation uses an FBC workflow with validation, Dockerfile generation, catalog image build and push, deprecated index.db detection, and ignores generated catalog artifacts.

Estimated code review effort: 3 (Moderate) | ~20 minutes

In `@Makefile`:
- Line 280: Update the image inspection check in the Makefile to grep for the
operators.operatorframework.io.bundle.mediatype.v1 label and assert its
registry+v1 value, replacing the current test.mediatype.v1 check so the gate
validates the bundle media type.

@svghadi, @jgwest, can you please take a look?

This is a first step in the above Epic, addressing what I consider are the most pressing aspects before the OLMv0 deprecation.
