refactor: migrate proxy setting guard to sysproxy-rs crate (#5287)

* Refactor proxy management: Remove EventDrivenProxyManager and async_proxy_query

- Removed the EventDrivenProxyManager and its related event-driven proxy management logic.
- Replaced usages of AsyncProxyQuery with direct calls to sysproxy for fetching system and auto proxy configurations.
- Cleaned up constants by removing unused default proxy host.
- Updated sysopt to eliminate calls to the removed EventDrivenProxyManager.
- Adjusted logging and proxy state management to reflect the removal of event-driven architecture.
- Simplified the core module structure by removing unnecessary module imports.

* refactor: remove bypass module for cleaner network configuration

* feat: update sysproxy to version 0.4.0 and add guard feature; refactor sysopt for improved proxy management

* feat(windows/sysproxy): unify guard-type handling and auto-restore drift

* refactor(config): remove commented-out code for SysProxy update flag
