Investigate binary size

Binary size is around 180Mb, seems excessive. Hypotesis: smacker/go-tree-sitter includes grammars for lots of languages, could it be that they are all included in the binary? Maybe try https://github.com/tree-sitter/go-tree-sitter which does not include any embedded grammar. Running `gsa` on the binary shows this: <img width="1403" alt="Image" src="https://github.com/user-attachments/assets/b58092cd-b66c-48d2-bce5-ab9ff808b174" />
