BREAKING CHANGE: drop all sqlite support

[grokspawn]

Description of the change:
A view of how opm would look if we drop all SQLite support (which has been deprecated for 4+ years).
An earlier iteration of this PR also dropped the model intermetiate package, but findings of current bugs as well as the added complexity suggest we'd be better off doing a separate PR for it.

Motivation for the change:

Reviewer Checklist

• Implementation matches the proposed design, or proposal is updated to match implementation
• Sufficient unit test coverage
• Sufficient end-to-end test coverage
• Docs updated or added to /docs
• Commit messages sensible and descriptive

Pull request overview

This PR removes the long-deprecated SQLite-based catalog/index path from operator-registry and drops the (internal/alpha) channel priority property support, leaving the file-based catalog (FBC / declarative config) path as the supported workflow.

Changes:

• Remove SQLite implementation code, migrations, testdata, and sqlite-backed CLI surfaces (opm index, opm registry, standalone servers, sqlite migration command).
• Remove channel priority property construction in the alpha property layer.
• Adjust build configuration/dependencies to reflect the removal (tags/CGO changes, module dependency cleanup).

codecov/project results are misleading, because there are at least a couple of areas where we went 75% --> 100%, but the delta is captured as 0%.

[joelanford]

We may be able to drastically simplify our github release workflows now that the CGO dependency is no more!

Totally do-able in a follow-up, but don't want that to be overlooked!

Makefile:71

• The static target injects its own -tags "json1" via extra_flags, but the build recipes already pass -tags=$(TAGS). That results in two -tags flags, where the latter (json1) can override $(TAGS) and unintentionally drop required build tags like containers_image_openpgp during make static (used by upstream-builder.Dockerfile). Since this PR removes SQLite support, the extra json1 tag should be removed (or appended to TAGS if still truly needed).

README.md:103

• This section still refers to an "index" even though the preceding steps now describe building and serving a file-based catalog (FBC) image. Updating the heading/text helps avoid confusion for users now that SQLite/index workflows are removed.

# Using the index with Operator Lifecycle Manager

To add an index packaged with `operator-registry` to your cluster for use with [Operator Lifecycle Manager](https://github.com/operator-framework/operator-lifecycle-manager) (OLM) create a `CatalogSource` referencing the image you created and pushed above:

Agreed. There are a few things we can iterate on after this lands.

changes look good to me overall, will wait for others to review as well
