- Add try_idle_context() to ContextSwitchPercpu (switch.rs) Cross-CPU paths (steal_work, migrate_one_context) use try_idle_context() instead of idle_context() to avoid panic when APs haven't called context::init() yet. Returns Option<context::Arc> instead of panicking. - Pin rust-toolchain.toml to nightly-2026-04-11 - Remove build artifacts (kernel, kernel.all, kernel.sym) from git tracking - This fixes the boot panic that occurred during multi-CPU scheduling
