feat: IMAP mail sync with thread-to-contact matching (PRD §6.1)

Real IMAP connection via imapflow library:
- Connects to IMAP server (IMAPFlow, TLS on port 993)
- Fetches recent messages (configurable limit, default 20)
- Extracts: from, fromEmail, subject, date, snippet (200 chars)
- Thread-to-contact matching (PRD §6.1):
  1. Match sender email against persons table
  2. If no person match, extract domain and match against company.website
  3. Returns matchedCompany + matchedPerson for each email
- Audit-logged (action: crm.mailsync:imap)
- Zod validated (host, port, user, password, folder, limit)
- 502 on IMAP connection failure with detail
- 400 on validation failure

Tested: invalid creds → 502 'IMAP connection failed', missing host → 400

+# Social Card Map / Travel Template
+
+Use when location, route, itinerary, distance, neighborhood, or place relationship is central to the card.
+
+## Core Rule
+
+A map card must clarify spatial relationships. Do not add a map shape only as decoration.
+
+## Structure Options
+
+- route map + 3 stops
+- neighborhood map + recommendation labels
+- day itinerary + simple path
+- place card + mini map + travel note
+- comparison: two areas / two routes
+
+## Must Do
+
+- Simplify geography aggressively.
+- Label only necessary places.
+- Use a clear route/path hierarchy.
+- Include context: city, date, duration, walking/driving/transit if relevant.
+
+## Avoid
+
+- Map details too dense for phone viewing.
+- Fake exact map data when none is provided.
+- Decorative map backgrounds unrelated to content.
+
+## Pattern Source Rule
+
+Read this `SKILL.md` first. Do **not** read `pattern.html` by default.
+
+Read `pattern.html` only when you need concrete layout rhythm, spatial relationships, or interaction/annotation behavior that this markdown cannot fully specify. When read, extract patterns only; do not copy DOM, CSS classes, exact spacing, placeholder copy, or styling wholesale.
