Refactor syscall modules to use async/await patterns

- Updated `DisplaySyscall` to use `tokio::io::AsyncWriteExt` for asynchronous text output.
- Refactored `FsSyscall` to read files asynchronously with offset and length handling.
- Modified `MemorySyscall` to use `tokio::task::spawn_blocking` for database operations, allowing async access to SQLite.
- Enhanced `NetworkSyscall` to utilize `reqwest` for HTTP requests, replacing the previous `curl` command execution.
- Improved `ProcessSyscall` to manage subprocesses with async tasks for stdin, stdout, and stderr handling.
- Updated `TimerSyscall` to simplify timer management.
- Adjusted plugin implementations for better async support and error handling.
- Added `tokio-stream` and `tracing-subscriber` dependencies to `Cargo.toml` for enhanced async stream handling and logging.
