fix(macos): resolve build warnings, memory leaks, and thread safety

Browse Source 
- Remove deprecated `cocoa` crate in favor of direct `objc` usage to fix future-incompatibilities warning from `block` dependency.
- Fix irrefutable `if let` pattern warning in macOS `SleepPreventer::Drop`.
- Fix memory leaks by properly releasing `alloc`-ed `NSString` and `NSAppleScript` objects.
- Fix AppKit thread safety by routing dock badge updates to the main thread via `run_on_main_thread`.
