pub fn compute_complexity(content: &str, language: Language) -> Option<u32>Expand description
Compute the cyclomatic complexity score for a chunk of source code.
Returns Some(score) where score >= 1 for supported languages,
or None if the language is unsupported or parsing fails.
The score is 1 + count(branch_nodes) where branch nodes are
language-specific AST nodes representing control flow decisions.
