//! Generated-file detection for symbol-disambiguation down-ranking.
//!
//! This is the Rust counterpart to `generated-detection.ts`. It is deliberately
//! path-only: generated files stay in the graph, but callers can rank them
//! behind hand-written implementations with the same name.
//!
//! 这里不读取文件内容，避免搜索/排序路径触发额外 I/O；判断结果只作为
//! 排序降权信号，不影响文件是否被索引。
