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

+# Interview Designer
+
+**Evidence-Based Interview Planning**
+
+Design interview questions using Scorecard → Forensic Scan → Future Simulation. Avoid confirmation bias and produce structured interview guides (Scorecard + Red Flags/Green Signals + Pressure Tests + Future Scenarios) with Geoff Smart, Lou Adler, and Daniel Kahneman as the default expert panel.
+
+---
+
+## When to Use This Skill
+
+Use this skill when:
+
+- You need to design interview questions for a specific role
+- You want to avoid confirmation bias in interview planning
+- You're creating a structured interview guide (Scorecard + Questions + Pressure Tests)
+- You need to balance past validation with future simulation
+
+---
+
+## Methodology: Scorecard → Forensic → Future
+
+| Phase           | Expert        | What You Define                                                                 |
+|-----------------|---------------|-----------------------------------------------------------------------------------|
+| **1. Scorecard**| Geoff Smart   | Mission, Outcomes, Competencies — *before* looking at any resume                 |
+| **2. Forensic Scan** | Smart + Domain | Resume gaps vs. highlights; "Too Good To Be True" / "Driver vs Passenger" heuristics |
+| **3. Future Simulation** | Lou Adler  | Performance problems the candidate would face in your context; week-one scenarios |
+
+---
+
+## What You Get
+
+| Output            | Template                           | Purpose                                              |
+|-------------------|------------------------------------|------------------------------------------------------|
+| **Interview Guide** | `templates/interview_guide_template.md` | Scorecard + Red Flags/Green Signals + Pressure Tests + Future Scenarios |
+
+The guide includes both concerns (**Red Flags**) and highlight verification (**Green Signals**) for objective assessment.
+
+---
+
+## Design Principles
+
+1. **Cannot Be Memorized** — Questions force real-time thinking (simulation) or concrete recall (pressure test).
+2. **Forced Trade-offs** — Choose between two "correct" options to surface values, not just knowledge.
+3. **Detail Granularity** — Probe to "what exact words did you say" or "what diagram did you draw."
+
+---
+
+## Quick Reference
+
+| Interview Goal      | Question Type       | Example                                                                 |
+|---------------------|---------------------|-------------------------------------------------------------------------|
+| Validate past claims| Pressure Test (STAR) | "Walk me through the specific metrics you tracked and how you used them." |
+| Predict future fit  | Future Simulation   | "Here's our Q1 challenge. How would you approach it in your first week?" |
+| Detect blind spots  | Trade-off Question  | "Speed vs. quality — which would you sacrifice here, and why?"         |
