v0.6.0

• Lots of fixes and optimizations. No, I didn't get help from AI but God's loving instruction ❤️
• Removed my connection timeout mechanism as libvncclient's already is fine and mine was causing minor issues
• Fixed Windows crash, caused by use-after-free which didn't show up on other platforms
• Removed wonky app / item options and F8 controls-referencing, using file-level structs and not the lame consts_enums defines
• Fixed child windows bug where closing with window-manager close button didn't fire necessary handling logic, preventing child windows to open afterward
• Commented out inactive timeout stuff but leaving for possible implementation in the future
• Replaced old C-style num-to-string code with std::to_string()
• Reformatted and updated help screen text
• Successfully building on all but OpenIndiana. It's possible my OpenIndiana VM isn't updated correctly or is corrupt 🤷‍♂️
