/**
 * Call Graph Analyzer
 *
 * Performs static analysis of function calls across source files using tree-sitter.
 * Supports TypeScript/JavaScript, Python, Go, Rust, Ruby, Java, Swift — no LLM, pure AST.
 *
 * Produces:
 *  - FunctionNode[]  — all identified functions/methods
 *  - CallEdge[]      — resolved function→function call relationships
 *  - Hub functions   — high-fanIn nodes (called by many others)
 *  - Entry points    — functions with no internal callers
 *  - Layer violations — cross-layer calls in the wrong direction

 * that is absent. This reports that, so a caller can tell "the grammar is not here" apart from
 * "the grammar is here and produced nothing", which are the same empty result but very different
 * facts. `false` also means "not attempted yet"; drive an extraction first.
 *
 * Exists because the two are indistinguishable at the assertion site: when `tree-sitter-kotlin`
 * failed to install in CI, nine tests failed with messages like `expected [] to include 'main'`,
 * which reads exactly like a broken extractor and cost real time to diagnose as an install
 * problem. The grammars are `optionalDependencies` BY DESIGN (`loadGrammarSoft`, restricted
