Subject: [PATCH 2/2] fix: resolve all borrow checker errors in kernel - Fixed double mutable borrow in fs/ramfs.rs (create_file, create_dir) - Fixed signature borrow conflict in quantum/pqcrypto.rs - Fixed self.amplitudes double borrow in quantum/mod.rs (pauli_x) - Fixed self borrow conflict in shell/menu.rs (handle_event) - Fixed multiple borrow conflicts in shell/window.rs - Fixed literal out of range in lib.rs - Added workspace directive to kernel Cargo.toml - All kernel modules now compile successfully Phase 3 features included: - Update system module - Archive support (zip, tar, compression, encryption) - UI/Shell system (desktop, taskbar, menu, explorer, window) - Post-quantum cryptography module - Additional filesystems (ramfs, devfs, procfs) --- iso_build/kernel/Cargo.lock
