Function path_last

internal/cbm/extract_imports.c:94–108

Helper: get last path component as local name. Recognizes every separator used across the supported import syntaxes: '/' (Go / TS / JS paths), '.' (Java / Kotlin / C# / Python dotted names), '::' (Rust / C++ scope), '\\' (PHP namespaces). The last separator of any kind wins, so "std::collections::HashMap" → "HashMap" and "App\\Http\\Controller" → "Controller".

//   kind wins, so "std::collections::HashMap" → "HashMap" and
//   "App\\Http\\Controller" → "Controller".
