Fixes #87. PR #58 incorrectly added gopkg.in/yaml.v3 (abandoned library) instead of github.com/goccy/go-yaml as required by issue #57. Changes: - Replace gopkg.in/yaml.v3 with github.com/goccy/go-yaml v1.19.2 - Update review/persona.go to use goccy/go-yaml API: - parser.ParseBytes for AST-based depth/node count checking - yaml.Strict() decoder option instead of KnownFields(true) - ast.Node types instead of yaml.Node for tree walking - Update review/persona_test.go to use ast types for cycle tests - Remove gopkg.in/yaml.v3 from go.mod and go.sum All existing YAML tests pass with the new library.
