Adds tests/harness/docker-compose.yml running GreenMail 2.1.12 (digest-pinned)
with SMTP 3025, IMAP 3143 and the API bound to 127.0.0.1 only, plus a
config/harness-imap.yml scanner profile and harness README. Auth is disabled
and no users are declared, so a mailbox is created on first login and per-test
users need no provisioning.
GreenMail standalone offers no STARTTLS, only plaintext or implicit TLS, while
SMTPProvider hardcoded starttls() -- so no send could reach it. SMTPProvider
now takes a security mode via EMAIL_CONNECT_SMTP_SECURITY, defaulting to
starttls. plaintext is refused for any non-loopback host, and hostnames are
never resolved to decide that, so a misconfigured deployment fails at startup
rather than sending credentials in the clear. Trusting GreenMail's self-signed
cert was rejected as the wider risk; see DECISIONS.md.
Verified end to end against the live harness: SMTPProvider.send -> GreenMail ->
ImapMailboxSource, and the documented scan-mailbox CLI. Suite: 52 passed with
the harness down.

Plans a Maildir mailbox source, a containerized SMTP/IMAP test server,
deterministic test-user mailboxes, and end-to-end send-and-scan integration
tests, so automated test environments get mail accounts for test users without
a live provider.
Records the decision to use a purpose-built test server rather than integrating
s/qmail, and keeps bounce/complaint/deferral evidence on fixtures plus an
optional provider simulator tier.

Ship the railiance01 deploy package (OpenBao/ESO custody, NetworkPolicy,
probes), provider failure classification and suppression, T04 unit and live
proof, and non-secret NK-WP-0024 hand-back evidence. Workplan finished.
