Foundation for the passwordless auth migration (ADR-0028 Phase A) and the BDD email-parallel strategy (ADR-0030). This PR ships only the infrastructure — no auth code yet ; that lands in subsequent PRs. Changes: - docker-compose.yml: add mailpit service (axllent/mailpit:latest), SMTP on :1025, HTTP UI/API on :8025, MP_MAX_MESSAGES=5000 - pkg/email/sender.go: provider-agnostic Sender interface + Message struct - pkg/email/smtp_sender.go: SMTPSender implementation (net/smtp), with Mailpit-friendly defaults (localhost:1025, no TLS, no AUTH), context- aware Send with timeout, supports plain text and multipart/alternative - pkg/config: AuthConfig.Email field + EmailConfig struct + GetEmailConfig getter + 7 new env vars (DLC_AUTH_EMAIL_*) + defaults - documentation/EMAIL.md: setup, inspection (UI + API), code examples, cross-refs to ADR-0028/0029/0030 Tests (pkg/email/smtp_sender_test.go): - validateMessage rejects missing fields, accepts minimal - buildRFC5322 plain-text path produces single-part text/plain with expected headers - buildRFC5322 multipart path produces multipart/alternative with both parts and a closing boundary - buildRFC5322 custom headers are canonicalised (lowercase keys → Title-Case) - NewSMTPSender defaults are Mailpit-friendly - Send respects context cancellation (no 10s wait when ctx cancelled) Race detector clean. Build clean. Vet clean. Out of scope for this PR (Phase A.2+): - BDD email-steps helper package (pkg/bdd/mailpit/, pkg/bdd/steps/email_steps.go) - magic_link_tokens table + repository - magic-link/request and magic-link/consume HTTP handlers - BDD scenarios for the magic-link flow
