Plan for a 3.0.x release

Problem/Motivation

Drupal Core is going to be deprecating Annotation based plugin discovery (see https://www.drupal.org/node/3395582 → + https://www.drupal.org/node/3395575 → ). This module provides a plugin-based API, and will be affected by this backwards-incompatible change.

Proposed resolution

Since this is a disruptive change that will impact module developers, we must create a new SEMVER-major branch, convert the annotation based plugin system to use attributes, and make any other backwards-incompatible changes as needed.

Remaining tasks

1. Declare support for drupal/core: ^10.2 only
2. Convert plugin manager + plugins to use attributes vs annotations
3. Clean up todo items added by https://www.drupal.org/project/oembed_lazyload/issues/3413985 ✨ Provide an extensible mechanism for thumbnail configuration and customization Needs work
4. Get a release out early to allow module developers ample time to update before dropping 2.0.x support / Drupal 10 end of life
