Bug Fixes

• Fixed an infinite loop that could happen in some grammars during error recovery if the end of the file was reached.
• Fixed a parser-generation error where internal character set constants were given external linkage, which could cause linking errors on some platforms if multiple Tree-sitter parsers were linked into the same application.

Bug Fixes

• Fixed a crash that could occur when loading WASM-compiled languages that were generated with an earlier version of the Tree-sitter CLI (#4210).
• Fixed incorrect tokenization when using WASM-compiled languages, if the language's external scanner did not assign to result_symbol (#4218)
• Fixed an infinite loop that could occur if external scanners returned empty extra tokens (#4213)

Build

• Decreased the rustc version required to build the tree-sitter-languages and tree-sitter crates (#4221)
