/**
 * Parse source code using tree-sitter's string input path with an adaptive
 * native buffer size.
 *
 * The callback input API receives byte offsets. Returning JavaScript string
 * slices from those byte offsets is unsafe for UTF-8/multi-byte content and has
 * caused native tree-sitter crashes in large repositories. Use the stable string
 * input path instead and raise tree-sitter's internal buffer for large files.
 *
 * @param content - Full source file content as UTF-8 string
 * @param oldTree - Optional previous tree for incremental parsing (must call tree.edit() first)
 * @returns Parsed syntax tree
