Installs arcane-cli in a GitHub Actions job so later workflow steps can run the Arcane CLI.

Install the latest Arcane CLI release:

steps:
  - uses: getarcaneapp/setup-cli@v1
  - run: arcane-cli --version

Install Arcane CLI v1.19.5:

steps:
  - uses: getarcaneapp/setup-cli@v1
    with:
      version: 1.19.5
  - run: arcane-cli --version

Configure the CLI with workflow secrets before calling an Arcane server:

steps:
  - uses: getarcaneapp/setup-cli@v1
    with:
      version: 1.19.5
  - run: |
      arcane-cli config set server-url "$ARCANE_SERVER_URL"
      arcane-cli config set api-key "$ARCANE_API_KEY"
      arcane-cli projects list
    env:
      ARCANE_SERVER_URL: ${{ secrets.ARCANE_SERVER_URL }}
      ARCANE_API_KEY: ${{ secrets.ARCANE_API_KEY }}

• version - Optional. Arcane CLI version to install. Defaults to latest. Accepts latest, exact versions like 1.19.5 or v1.19.5, and semver ranges like 1.x.
• github-token - Optional. GitHub token used for release API calls. Useful if your workflow hits unauthenticated GitHub API rate limits.

• version - Resolved Arcane CLI version that was installed.
• path - Directory added to PATH.
• cache-hit - true when the tool came from the runner tool cache, otherwise false.

This action only installs arcane-cli. It does not request GitHub OIDC tokens, exchange credentials, or write Arcane config automatically.
