Fix Tmux Detection & Setup.

Download v1.23.3

The download page always has the newest build; installers for this version are on GitHub.

Find tmux on more systems — the app now searches your login shell PATH in addition to the app PATH, so tmux is discovered even when it lives in a custom Homebrew, MacPorts, or Linux package manager location
Settings shows platform-specific guidance — the Libraries panel now tells you exactly where the app looked and how to install tmux for your operating system
Missing tmux diagnostics are clearer — when tmux is not found, the log shows which package managers and paths were checked, making it easier to fix the setup

Fixed image annotation toolbar missing in production builds — drawing on attached screenshots before sending them to an AI agent now loads correctly in packaged releases, not just in development
