Better-Auth Disposable Email Blocker

The `better-auth-no-disposable-emails` package is a plugin for the `better-auth` authentication library, designed to prevent users from signing up or signing in with temporary or disposable email addresses. It integrates with `better-auth`'s plugin system, intercepting specified authentication endpoints (e.g., `/sign-up/email`) and validating the submitted email against a comprehensive list of known disposable email providers, powered by the `mailchecker` library. The current stable version is 0.2.0, indicating it's relatively new and in active development, though a specific release cadence isn't published. Its key differentiator is its seamless integration with `better-auth`, providing a configurable and extensible solution to enhance user quality and reduce spam registrations by blocking transient email accounts.
