fix: remove tree-sitter-go to resolve peer dependency conflict

- tree-sitter-go@0.23.4 peer depends on tree-sitter@^0.21.1
- Conflicts with tree-sitter@0.22.4 used by tree-sitter-python
- Go AST already falls back to generic export/deps extraction
- Add .npmrc with legacy-peer-deps=true as safety net
- npm install --omit=dev now works cleanly
