Pin tree-sitter to 0.20.x because tree-sitter-languages 1.10.x is incompatible with tree-sitter 0.21+. The 0.21+ API changed Parser() and Language() constructors, causing '__init__() takes exactly 1 argument (2 given)' errors on all file parsing operations. This fix restores selective indexing functionality which relies on TreeSitter for code parsing and symbol extraction.

Summary
Parser()andLanguage()constructors, breaking tree-sitter-languages__init__() takes exactly 1 argument (2 given)errors on all file parsingProblem
Selective indexing was completely broken because TreeSitter failed to parse any files:
This resulted in 0 symbols being extracted, making the "top 20% important files" selection return 0 files.
Solution
Pin tree-sitter to
>=0.20.0,<0.21.0until tree-sitter-languages is updated to support the new API.Test plan
