runningshrimp 6c2652b509 Remove 'alloc' feature flag from nos-syscalls and nos-services crates 
- Remove all #[cfg(feature = "alloc")] conditional compilation attributes
- Unify memory allocation patterns to use alloc crate types consistently
- Ensure all memory allocation goes through kernel services
- Update ServiceInfo struct to use String instead of conditional types
- Remove duplicate register_handlers implementations
- Update error handling to use String-based errors consistently

runningshrimp 80ca420ac4 P0-003: 重构syscall模块为多文件结构 
将1020行的syscall.rs拆分为多个<500行的模块:
- syscalls/mod.rs (310行): 分发器和通用定义
