Fix test failures from incorrect parameter and outdated selectors

[Copilot]

Two test files were failing: find_rightClick.spec.json and screenshot.spec.json. Root causes were a bug in driver retry logic and outdated DuckDuckGo page selectors.

Changes

• Fixed getDriverCapabilities parameter mismatch (src/tests.js:564)

  • Changed config: config → runnerDetails: runnerDetails in headless retry path
  • Function signature expects { runnerDetails, name, options }, not config

• Updated DuckDuckGo selectors (test/artifacts/)

  • Changed #searchbox_input → input[name="q"] in test specs
  • Old selector no longer exists on current DuckDuckGo page

  caps = getDriverCapabilities({
-   config: config,
+   runnerDetails: runnerDetails,
    name: context.browser.name,
    options: { ... }
  });

The Windows/macOS compatibility improvements (port checking, hostname detection, platform-specific error messages) remain unchanged.
