📄 Description

Summary by cubic

Adds an optional usernameAvailabilityChecker to the username plugin to support external availability checks before the database lookup. This prevents externally reserved names from appearing as available in isUsernameAvailable.

  • New Features
    • Added usernameAvailabilityChecker option (sync or async). Return false to mark a username as unavailable.
    • Runs before the DB query and uses the existing normalizer.
    • isUsernameAvailable now respects external reservation logic.
    • Added tests covering reserved names like “admin” and non-reserved names.

Written for commit f422d96309. Summary will update automatically on new commits.

Fixes #6579
