Function generate_function_name

src/code_actions/extract_function.rs:398–407

Generate a contextual name for the extracted function/method. The naming follows these heuristics (first match wins): 1. **Guard strategies** (`VoidGuards`, `UniformGuards`, `NullGuardWithValue`): `{enclosing}Guard` — the user extracted validation / precondition logic. 2. **`SentinelNull`**: `try{Enclosing}` — a "try" pattern where `null` signals failure. 3. **`TrailingReturn` with `new ClassNam
