anti 3ee55ec341 feat(emailgen): Ollama-driven fake email worker for IMAP/POP3 deckies
Second orchestrator worker (decnet emailgen) that drips persona-driven,
threaded, multi-language fake emails into running mail deckies.  Personas
live on Topology.email_personas; topology-wide language_default falls
through to any persona that doesn't pin its own.  Em-dashes are
suppressed at the prompt layer by default and only lifted for personas
explicitly marked uses_llms_heavily — em-dashes are an LLM tell and a
flat corpus of em-dashed mail is a giveaway.

EML delivery writes into /var/spool/decnet-emails/<thread>/<msg>.eml on
the mail decky via docker exec; wiring the IMAP/POP3 templates to read
from that spool (replacing the hardcoded _BAIT_EMAILS) is the next step.

"""Emailgen main loop.
Mirrors :mod:`decnet.orchestrator.worker` shape: same heartbeat, same
control listener, same fire-and-forget bus publish, same prune knob.
A wedged ollama call stalls only this worker, never the SSH-flavoured
orchestrator running alongside.
