/**
 * Extract symbol references from a chunk's content.
 *
 * This is a cheap, language-agnostic heuristic: find identifier-shaped tokens
 * that look like function calls (`foo(`), class instantiations (`new Foo`),
 * decorators, JSX components, or Java/C#-style type usages. We skip language
 * keywords and self-references.
 *
 * It's not a type resolver — matches are by name. Multiple functions with the
 * same name across files will all appear as "impacted" when queried. That's
 * good enough for PageRank boosting and impact analysis, and significantly
 * cheaper than running a real LSP.
