Better Convex v1.0.0-beta.3

• Add an opt-in workforce assurance baseline for business applications with
  verified email, bounded sessions, TOTP, recovery codes, enrollment and
  revocation controls, and replay-safe security operations.
• Add typed Better Auth email hooks for verification, password reset, and
  invitations while keeping delivery in application-owned Convex actions.
• Preserve request-bound authentication continuity across browser, Nuxt, and
  Convex boundaries without exposing credentials to client state or logs.
• Centralize workforce adapter policy so transport handlers remain thin and
  security rules have one source of truth.
