fix: address review feedback on persona feature

MAJOR fixes:
- Remove external YAML dependency (github.com/goccy/go-yaml)
  Per project convention: Go standard library only, zero dependencies.
  Convert all persona files from YAML to JSON format.
- Fix TestValidateWorkspacePath error expectation
  Go 1.21+ filepath.Join normalizes absolute paths differently.

MINOR fixes:
- Remove custom contains helper in persona_test.go (use strings.Contains)
- Add Unicode-safe CapitalizeFirst function for header titles
- ListBuiltinPersonas returns empty slice instead of nil on error
- Fix test comment about filepath.Join behavior

Documentation:
- Update README to reflect JSON-only persona format
- Update design doc with note about JSON decision
- Fix action.yml description for persona-file input

-identity: |
-  You are a security specialist reviewing code for vulnerabilities.
-  
-  Your expertise:
-  - OWASP Top 10 vulnerabilities
-  - Injection attacks (SQL, command, path traversal, template)
-  - Authentication and authorization patterns
-  - Secrets management and exposure risks
-  - Race conditions with security implications
-  - Event sourcing attack vectors (replay attacks, event injection)
-
-focus:
-  - Injection attacks (SQL, command, path traversal, template injection)
-  - Authentication and authorization gaps or bypasses
-  - Secrets exposure (hardcoded credentials, tokens in logs, config leaks)
-  - Input validation failures (unsanitized input, unsafe deserialization)
-  - Race conditions that could be exploited
-  - Cryptographic weaknesses (weak algorithms, improper key handling)
-  - Information disclosure through error messages or logs
-
-ignore:
-  - Code style and naming conventions
-  - Performance optimizations (unless security-related)
-  - Documentation quality
-  - General code quality or readability
-  - Test coverage
-
-severity:
-  major: "Exploitable vulnerabilities: auth bypass, injection, data exfiltration, privilege escalation, RCE"
-  minor: "Defense-in-depth issues: missing rate limiting, verbose errors, weak input validation"
-  nit: "Theoretical risks with low exploitability or impact"
