Fixes #333

Problem

parsePubspecNameVersion matched name:/version: lines by hand, so a trailing YAML comment (version: 1.0.0 # bump me) ended up in the parsed value.

Change

• Unmarshal pubspec.yaml into a small struct with go.yaml.in/yaml/v3 (already a dependency of this module), matching hc, which uses a YAML parser here.
• Remove the line-based extractPubspecField.
• Missing keys now return empty strings and fall through to the existing must contain non-empty 'name' and 'version' check, as in hc. Malformed YAML returns failed to parse pubspec.yaml: ....
• Add a table test covering trailing comments, quoted values, nested name/version keys, a missing key, and malformed YAML.

Module-only change (modules/har); no new dependencies.

Testing

go test ./pkg/har/ -run TestParsePubspecNameVersion in modules/har
