🎯 What: The src/mermaid/install.sh script used curl | bash to dynamically download and execute the NodeSource setup script to install Node.js. This vulnerability has been fixed.
⚠️ Risk: Executing arbitrary remote scripts as root is a significant security risk. If the upstream provider's domain is compromised, or a Man-in-the-Middle (MitM) attack occurs, malicious bash scripts could be injected and executed with root privileges during the devcontainer image build process, leading to full container compromise.
🛡️ Solution: The unsafe script download approach was completely removed. Instead, the installation was refactored to directly use the vendor's GPG keys and configure the native package manager repositories (/etc/apt/sources.list.d/nodesource.sources for Debian/Ubuntu and /etc/yum.repos.d/nodesource.repo for RHEL/CentOS). This eliminates the execution of an arbitrary remote script while providing a more robust, reliable, and secure installation pipeline for Node.js.

Removed unsafe execution of remote NodeSource setup scripts via `curl | bash`.
Instead of relying on brittle external scripts, the devcontainer feature now
directly configures native package manager repositories (APT and YUM) and
securely downloads the required GPG keys to fetch Node.js.

This resolves a critical vulnerability that allowed potential remote code
execution via MitM attacks or compromised upstream domains.
