fix: implement universal 50-character threshold for code indexing

- Changed MIN_BLOCK_CHARS from 100 to 50 in parser.ts
- Updated tests to expect single-block captures for small Go files
- Removed language-specific threshold logic
- Fixes Go files not being indexed due to high character threshold

Fixes #5367
