FileStatNative.rs

1//! Wire method `file:stat`. Returns VS Code's `IStat` shape via
2//! `metadata_to_istat`. Uses `symlink_metadata` to avoid following
3//! symlinks (matches Electron behaviour). Noise from benign ENOENTs on
4//! known VS Code probe paths is squelched via `IsBenignEnoent` +
5//! `DebugOnce`.
