Fix memory safety and error handling issues

[RAprogramm]

Summary

• Replaced all unwrap()/expect() calls with proper error handling
• Removed std::process::exit() in favor of graceful returns
• Added comprehensive safety documentation for unsafe Send/Sync implementations
• Documented Box::leak() usage and API constraints imposed by hyprland library
• Fixed clippy warnings (unused lifetime, type complexity)
• Added opt-level = 3 to release profile for maximum optimization

Changes

Error Handling

• cli/src/keyword.rs: Replaced unwrap() with match expressions and error messages
• cli/src/dispatch.rs: Added error handling for runtime creation
• hyde-ipc-lib/src/service.rs: Replaced expect() and std::process::exit with Result propagation

Process Management

• cli/src/listen.rs: Replaced std::process::exit(0) with graceful event counter that displays message when limit reached

Safety Documentation

• hyprland-lib/src/unsafe_impl.rs: Added module-level and per-implementation safety documentation explaining thread safety guarantees
• cli/src/dispatch.rs: Added documentation explaining Box::leak() usage due to hyprland API constraints
• cli/src/parsers.rs: Added documentation for memory leak acceptability in CLI context

Code Quality

• hyprland-lib/src/event_listener/shared.rs: Removed unused lifetime, added type alias for complex return type
• Cargo.toml: Added opt-level = 3 to release profile

Testing

All changes maintain existing functionality while improving safety and code quality.

Closes #52

@RAprogramm thanks for the PR.
I changed the base branch to dev. please restore hyprland-lib/src/unsafe_impl.rs as it's not really necessary. And please make sure to format files you change before pushing (or just run cargo fmt at root project dir). Currently rustfmt.toml doesnt apply to :

cli/src/flags.rs
cli/src/main.rs
cli/src/react_config.rs
