feat: update Cargo.toml for 2024 edition and optimize release profiles (#4681)

* feat: update Cargo.toml for 2024 edition and optimize release profiles

* feat: refactor environment variable settings for Linux and improve code organization

* Refactor conditional statements to use `&&` for improved readability

- Updated multiple files to combine nested `if let` statements using `&&` for better clarity and conciseness.
- This change enhances the readability of the code by reducing indentation levels and making the conditions more straightforward.
- Affected files include: media_unlock_checker.rs, profile.rs, clash.rs, profiles.rs, async_proxy_query.rs, core.rs, handle.rs, hotkey.rs, service.rs, timer.rs, tray/mod.rs, merge.rs, seq.rs, config.rs, proxy.rs, window.rs, general.rs, dirs.rs, i18n.rs, init.rs, network.rs, and window.rs in the resolve module.

* refactor: streamline conditional checks using `&&` for improved readability
