refactor: split CLI module into focused formatters and groupers

- Created cli/groupers/ViolationGrouper.ts for severity filtering
- Created cli/formatters/OutputFormatter.ts for violation formatting
- Created cli/formatters/StatisticsFormatter.ts for metrics display
- Reduced cli/index.ts from 484 to 260 lines (46% reduction)
- All 345 tests pass, CLI output identical to before
- No breaking changes

+
+### Version 0.8.0 - Secret Detection 🔐
+**Target:** Q1 2025
+**Priority:** CRITICAL
+
+Detect hardcoded secrets (API keys, tokens, credentials) using industry-standard Secretlint library.
+
+**🎯 SecretDetector - NEW standalone detector:**
+
+```typescript
+// ❌ CRITICAL: Hardcoded AWS credentials
+const AWS_KEY = "AKIA1234567890ABCDEF"  // VIOLATION!
+const AWS_SECRET = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"  // VIOLATION!
+
+// ❌ CRITICAL: Hardcoded GitHub token
+const GITHUB_TOKEN = "ghp_1234567890abcdefghijklmnopqrstuv"  // VIOLATION!
+
+// ❌ CRITICAL: SSH Private Key in code
+const privateKey = `-----BEGIN RSA PRIVATE KEY-----
+MIIEpAIBAAKCAQEA...`  // VIOLATION!
+
+// ❌ CRITICAL: NPM token
+//registry.npmjs.org/:_authToken=npm_abc123xyz  // VIOLATION!
+
+// ✅ GOOD: Use environment variables
+const AWS_KEY = process.env.AWS_ACCESS_KEY_ID
+const AWS_SECRET = process.env.AWS_SECRET_ACCESS_KEY
+const GITHUB_TOKEN = process.env.GITHUB_TOKEN
+```
+
+**Planned Features:**
+- ✅ **SecretDetector** - Standalone detector (separate from HardcodeDetector)
+- ✅ **Secretlint Integration** - Industry-standard library (@secretlint/node)
+- ✅ **350+ Secret Patterns** - AWS, GitHub, NPM, SSH, GCP, Slack, Basic Auth, etc.
+- ✅ **CRITICAL Severity** - All secret violations marked as critical
+- ✅ **Smart Suggestions** - Context-aware remediation per secret type
+- ✅ **Clean Architecture** - New ISecretDetector interface, SecretViolation value object
+- ✅ **CLI Integration** - New "🔐 Secrets" section in output
+- ✅ **Parallel Execution** - Runs alongside existing detectors
+
+**Secret Types Detected:**
+- AWS Access Keys & Secret Keys
+- GitHub Tokens (ghp_, github_pat_, gho_, etc.)
+- NPM tokens in .npmrc and code
+- SSH Private Keys
+- GCP Service Account credentials
+- Slack tokens (xoxb-, xoxp-, etc.)
+- Basic Auth credentials
+- JWT tokens
+- Private encryption keys
+
+**Architecture:**
+```typescript
+// New domain layer
+interface ISecretDetector {
+    detectAll(code: string, filePath: string): Promise<SecretViolation[]>
+}
+
+class SecretViolation {
+    file: string
+    line: number
+    secretType: string  // AWS, GitHub, NPM, etc.
+    message: string
+    severity: "critical"
+    suggestion: string  // Context-aware guidance
+}
+
+// New infrastructure implementation
+class SecretDetector implements ISecretDetector {
+    // Uses @secretlint/node internally
+}
+```
+
+**Why Secretlint?**
+- ✅ Actively maintained (updates weekly)
+- ✅ TypeScript native
+- ✅ Pluggable architecture
+- ✅ Low false positives
+- ✅ Industry standard
+
+**Why NOT custom implementation?**
+- ❌ No good npm library for magic numbers/strings
+- ❌ Our HardcodeDetector is better than existing solutions
+- ✅ Secretlint is perfect for secrets (don't reinvent the wheel)
+- ✅ Two focused detectors better than one bloated detector
+
+**Impact:**
+Guardian will now catch critical security issues BEFORE they reach production, complementing existing magic number/string detection.
