Move overlayfs implementation to Linux-specific directory and add comprehensive Linux filesystem support. This change introduces: Core Features: - Implement path traversal with lookup_layer_by_layer and lookup_segment_by_segment - Add copy_up functionality for promoting files from lower to upper layers - Support FICLONE ioctl for efficient Copy-on-Write operations - Implement Linux-specific file operations (fallocate, lseek, copyfilerange) - Add memory mapping support via setupmapping and removemapping Linux Integration: - Handle Linux-specific file descriptors and system calls - Support Linux xattr operations and mount point management - Implement proper device ID handling for Linux filesystems - Add CoW optimizations using Linux-specific filesystem features
- Remove ignore/debug from workspace members - Add #[cfg(test)] annotation to overlayfs test helper module - Remove redundant newline in devices/Cargo.toml
