test: replace Go-specific test with generic MIN_BLOCK_CHARS test

- Remove go-indexing-fix.spec.ts as requested in PR feedback
- Add generic test in parser.spec.ts to verify 50-character threshold
- Test ensures content under 50 chars is filtered, 50+ chars is indexed
- Applies to all languages, not just Go
