Add jj (Jujutsu) to dotfiles installation scripts using cargo-binstall

[Copilot]

Adds installation of jj (Jujutsu version control system) to both Linux installation scripts using cargo-binstall for faster binary installation.

Changes made:

• Added jj installation to install.sh for Codespaces/Linux environments
• Added jj installation to run_once_brew.sh.tmpl for chezmoi-managed Linux systems
• Added jj via Homebrew for macOS systems in the brew bundle
• Uses cargo-binstall instead of cargo install to download pre-built binaries rather than compiling from source
• Automatically installs cargo-binstall if not present
• Includes fallback to install Rust/Cargo if not available
• Uses --no-confirm flag to avoid interactive prompts during automated installation

Benefits:

• Significantly faster installation by using pre-built binaries
• Robust fallback chain: cargo-binstall → cargo install → Rust installation
• Works across macOS (via Homebrew) and Linux (via cargo-binstall) environments

@copilot use cargo-install instead of install

I'd like to clarify what you mean by "cargo-install". The current code uses cargo install which is the standard cargo subcommand for installing packages. I don't see a cargo-install command available.

Could you clarify:

1. Are you referring to a specific tool called cargo-install?
2. Do you want me to use a different installation method for jj?
3. Or is there a different approach you'd prefer for installing jj on Linux?

The current implementation uses cargo install --git https://github.com/martinvonz/jj jj-cli --bin jj which follows the standard cargo installation pattern.

Updated to use cargo-binstall instead of cargo install for faster jj installation. The changes install cargo-binstall automatically if not present and use cargo binstall --no-confirm jj-cli for the actual installation. This approach downloads pre-built binaries instead of compiling from source, making the installation much faster. (commit 5b4d5e7)
