capabilities 1.0.0-alpha1

First alpha release: named, translatable bundles of access for Drupal 11.3 and later.

• Site-wide capabilities that bundle Drupal permissions, assigned to roles and to users.
• Capabilities declared by modules in MODULE.capabilities.yml and defined by site builders in the UI.
• An overview under People and a per-user page showing why someone has each permission.
• No privilege escalation: nobody can assign a capability that grants permissions they do not hold.
• Scoped capabilities for access within one project, store or team, through the access policy API.

This is an alpha: the API may still change before a stable release, and alpha releases are not covered by the Drupal Security Team.
