refactor: modernize dependency stack and minimize footprint

- Migrate to native 'std::sync' primitives (LazyLock, OnceLock, RwLock).
- Replace 'parking_lot' with std library synchronization types.
- Switch from 'chrono' to 'std::time::SystemTime' for lightweight timestamps.
- Bump core dependencies: tokio (1.50.0) and rustls (0.23.37).
- Decouple 'solana-program' by utilizing 'solana-sdk' re-exports.
- Prune redundant crates: lazy_static, once_cell, chrono, maplit, and parking_lot.
- Remove unused dev-dependencies (criterion) and example-only utils (env_logger).
- Improve compile times and reduce supply chain attack surface.
