VERIFICATION METADATA STRUCTURE:

distributions->verification = {
  "commands": [                    // Array of verification commands to try (in priority order)
    {
      "binary": "python3",          // Binary name to execute
      "args": ["--version"],        // Arguments to pass
      "exit_code": 0,               // Expected exit code (0 = success)
      "pattern": "Python 3\.",      // Optional regex pattern to match in output
      "priority": 1,                // Lower = higher priority (try first)
      "optional": false             // If true, failure doesn't mean runtime unavailable
    }
  ],
  "always_available": false,       // If true, skip verification (shell, native)
  "check_required": true           // If false, assume available without checking
}

USAGE EXAMPLE:

To verify Python runtime availability:
1. Query: SELECT distributions->'verification'->'commands' FROM runtime WHERE ref = 'core.sensor.python'
2. Parse commands array
3. Try each command in priority order
4. If any command succeeds with expected exit_code and matches pattern (if provided), runtime is available
5. If all commands fail, runtime is not available

For always_available runtimes (shell, native):
1. Check distributions->'verification'->'always_available'
2. If true, skip verification and report as available
