1.0.0-alpha3

Compatibility and tooling. No change to the consent or rights-request data
model, so alpha2 sites upgrade without a database update.

EntityListBuilder::getDefaultOperations() now takes the CacheableMetadata
parameter Drupal 11.3 added. The module declares ^11, so the old signature
had drifted out of compatibility inside its own supported range and the
cacheability core passed was being dropped on the operations links.

GitLab CI is enabled and the pipeline is green: composer, composer-lint,
phpcs, phpstan, eslint, cspell and phpunit.

The README gains the Configuration section, which documents the permission
model, since the module has no settings form and permissions are what
actually govern its behavior.

Internals: constructor property promotion throughout, test storage fetched
per call rather than captured in setUp(), American spellings and a project
dictionary for Klaro, MeitY and StellerSight.
