Add Linux/macOS deployer script

[alirahimi818]

Summary by cubic

Adds a cross-platform Bash deployer for Linux/macOS with full Fastly Compute deploy/redeploy/manage flow and updated setup docs. Also hardens the installer with better curl error handling and a safer Node.js auto-install. This brings feature parity with the Windows installer.

• New Features

  • Deploy-Fastly-Linux.sh: interactive deployer for Linux/macOS.
  • Builds Wasm via npm run build; packages, uploads, validates, activates.
  • Creates/links a Config Store with TARGET_BASE, TARGET_HOSTNAME, RELAY_PATH.
  • Adds backend with configurable timeouts; supports create, redeploy, list, view, edit ENV, delete.
  • Runs health check and prints a ready-to-use VLESS URL.
  • Encrypts and saves the Fastly API token (AES-256) and tracks local deploy state.
  • Tries to auto-install Node.js if missing (apt, brew, dnf); requires bash, curl, python3, openssl, npm.
  • Ensures @fastly/js-compute runtime is present before build.

• Bug Fixes

  • add_fastly_backend and upload_fastly_package now check HTTP status codes and surface failures.
  • Node.js install is safer: downloads the NodeSource setup script to a temp file before sudo execution (no piping to sudo bash).
