feat(imap,pop3): full IMAP4rev1 + POP3 bait mailbox implementation
IMAP: extended to full IMAP4rev1 — 10 bait emails (AWS keys, DB creds,
tokens, VPN config, root pw etc.), LIST/LSUB/STATUS/FETCH/UID FETCH/
SEARCH/CLOSE/NOOP, proper SELECT untagged responses (EXISTS, UIDNEXT,
FLAGS, PERMANENTFLAGS), CAPABILITY with IDLE/LITERAL+/AUTH=PLAIN.
FETCH correctly handles sequence sets (1:*, 1:3, *), item dispatch
(FLAGS, ENVELOPE, BODY[], RFC822, RFC822.SIZE), and places body literals
last per RFC 3501.
POP3: extended with same 10 bait emails, fixed banner env var key
(POP3_BANNER not IMAP_BANNER), CAPA fully populated (TOP/UIDL/USER/
RESP-CODES/SASL), TOP (headers + N body lines), UIDL (msg-N format),
DELE/RSET with _deleted set tracking, NOOP. _active_messages() helper
excludes DELE'd messages from STAT/LIST/UIDL.
Both: DEBT-026 stub added (_EMAIL_SEED_PATH env var, documented in
DEBT.md for next-session JSON seed file wiring).
Tests: test_imap.py expanded to 27 cases, test_pop3.py to 22 cases —
860 total tests passing.
