Adds the tests/harness helper package: address(), available(), reset(),
users(), smtp_provider() and mailbox_config().
Tests address mailboxes as harness.address("<test name>"), which slugs the name
under the RFC 2606 reserved harness.email-connect.test domain, so distinct test
names cannot collide and a stray send cannot leave the host. No provisioning
call is needed -- the auth-disabled harness creates the mailbox on first login.
reset() drops every user and message via GreenMail's service reset; the next
login recreates the mailbox empty. It is documented to run at test start so a
crashed test cannot leak state forward, and it is global, so resetting tests
cannot run in parallel against one harness.
Suite: 64 passed with the harness up, 61 passed + 3 skipped with it down.

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.
