Add email notifications: agents send mail when human action needed

New: scripts/notify.py — sends via SMTP (notify@marcus-law.co.il → paperclip+chaim@marcus-law.co.il)
Updated: HEARTBEAT.md — agents must send email when waiting for human decision

Triggers: outcome choice, direction approval, QA failures, review ready.
