Railbase core v0.5.12

• CLI: persona-first launcher — bare railbase leads with Start Railbase (serve) as the Enter-default; New project (init) is the explicit developer fork. The serve ready-banner now points operators at the Marketplace (no code needed).
• Mailer: works out of the box in dev — auto-detects a local SMTP catcher (MailHog/Mailpit).
