Module imap 

IMAP server implementation

This module implements an IMAP (Internet Message Access Protocol) server that allows LLM control over email retrieval and mailbox management.

Key points:

• IMAP4rev1 commands parsed by hand into (tag, command, args). There is no imap-codec and no grammar: anything the split does not model (literals, continuations, quoting) is passed to the model as raw text.
• Session state management (NotAuthenticated -> Authenticated -> Selected -> Logout)
• Plain TCP only. An ImapServer::spawn_with_tls used to sit here advertising IMAPS on 993; nothing called it and it could not have worked - it fed a concatenated PEM string to Identity::from_pkcs12, which only accepts DER PKCS#12 - so it was removed rather than left as an implemented-looking feature.
• No mailbox storage: the model answers LIST/FETCH/SEARCH from its instruction and memory.
