- F15: i18n foundation with next-intl (EN/FR), cookie-based locale, language switcher

Schema: 12 new models, field additions to User, Project, ProjectFile, LiveVotingSession, LiveVote, MentorAssignment, AuditLog, Program
New routers: roundTemplate, message, webhook (registered in _app.ts)
New services: email-digest, webhook-dispatcher
New cron endpoints: /api/cron/digest, /api/cron/draft-cleanup, /api/cron/audit-cleanup
