Fix package manager detection and add shell-only workflow

- Add robust package manager auto-detection (apk, apt-get, yum, dnf)
- Support for Alpine, Debian/Ubuntu, CentOS/RHEL, Fedora
- Create shell-only.yml workflow with no GitHub Actions dependencies
- Update all workflows to handle different runner environments
- Comprehensive error handling and fallback mechanisms
- Updated documentation with new troubleshooting guidance

Resolves:
- "apk: command not found" errors
- "node: executable file not found" errors
- Compatibility with various Forgejo runner configurations

 ### Common Issues
 
-1. **Node.js executable not found error**
+1. **Package manager not found / Node.js executable not found error**
    ```
+   /var/run/act/workflow/0: line 2: apk: command not found
    OCI runtime exec failed: exec failed: unable to start container process: 
    exec: "node": executable file not found in $PATH: unknown
    ```
    **Solutions**:
-   - **Fixed in main workflows**: `ci.yml`, `test.yml`, `build.yml`, and `docker.yml` now install Node.js before checkout
+   - **Recommended**: Use `shell-only.yml` (pure shell, no actions, most compatible with any runner)
+   - **Fixed in main workflows**: `ci.yml`, `test.yml`, `build.yml`, and `docker.yml` now auto-detect package manager
    - Alternative: Use `node-ruby.yml` (Node.js base image with Ruby)
-   - Alternative: Use `simple.yml` or `minimal.yml` (shell-based, no Node.js actions)
+   - Alternative: Use `simple.yml` or `minimal.yml` (shell-based, limited actions)
-   - Manual fix: Add Node.js to Ruby Alpine: `apk add --no-cache nodejs npm`
+   - Check your Forgejo runner configuration and container image support
 
 2. **Actions not running**
    - Check if Repository Actions are enabled
