[lint-monster] Refactor long functions in pkg/parser package (80+ violations)

[github-actions]

Summary

The pkg/parser package contains approximately 80 functions exceeding the 60-line limit. These should be broken down into smaller, more testable units.

Affected Functions (Sample - See full list in logs)

• frontmatter_content.go:67 — ExtractFrontmatterFromContent (99 lines)
• frontmatter_hash.go:46 — marshalSorted (69 lines)
• frontmatter_hash.go:317 — extractImportsFromText (74 lines)
• github_urls.go:56 — ParseGitHubURL (134 lines)
• import_bfs.go:21 — processImportsFromFrontmatterWithManifestAndSource (492 lines)
• import_field_extractor.go:152 — prepareFrontmatter (123 lines)
• import_field_extractor.go:417 — extractActivationFields (93 lines)
• import_field_extractor.go:565 — extractFeatureAndObservabilityFields (84 lines)
• import_field_extractor.go:1136 — substituteImportInputsInContent (84 lines)
• And 70+ more functions...

Refactoring Strategy

1. Identify responsibilities — Group logic by domain (imports, validation, extraction)
2. Extract helper functions — Break long functions into 40-60 line components
3. Maintain readability — Use descriptive function names that clarify intent
4. Preserve behavior — No functional changes, only structure
5. Add tests — Ensure new helpers have dedicated unit tests

Validation

Run make golint-custom after refactoring to verify all pkg/parser lint violations are resolved.

Expected Outcome

All functions in pkg/parser reduced to ≤60 lines without functional changes.

Zero new lint errors introduced.
