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.

Adds MaildirMailboxSource reading new/ and cur/, wired through
source.maildir_dir and mailbox.protocol: maildir. Message identity is the
Maildir unique name without its :2,FLAGS suffix, so it survives the new/ to
cur/ move; it is carried on MailboxSourceMessage.dedup_uid and appended to the
message dedup key only when set, leaving fixture and IMAP keys unchanged.
Cursor ordering parses the Maildir delivery time instead of comparing names
lexically. mark_seen and a missing directory are rejected, matching the
read-only IMAP contract.
Also fixes the parse-failure path, which keyed identity on raw_message_ref.
A new/ to cur/ move rewrites that ref, so an unparseable message re-registered
as new on every rescan; it now prefers the source uid when one exists.
