feat: add USE_OWN_LOCAL_BINARY_PROCESS option to control local binary usage

[ruturaj-browserstack]

This pull request introduces a new configuration option, USE_OWN_LOCAL_BINARY_PROCESS, to allow users to use their own BrowserStack Local binary process instead of starting a new one. The changes include updates to the configuration class, conditional logic in the local binary setup, and error handling in the accessibility scanner. Below is a summary of the most important changes:

Configuration Updates:

• Added a new property, USE_OWN_LOCAL_BINARY_PROCESS, to the Config class in src/config.ts, allowing users to specify whether to use their own BrowserStack Local binary process. This is set based on the environment variable USE_OWN_LOCAL_BINARY_PROCESS. [1] [2]

Local Binary Setup:

• Updated the ensureLocalBinarySetup function in src/lib/local.ts to skip the setup process if USE_OWN_LOCAL_BINARY_PROCESS is enabled, logging a message to indicate this behavior.

Accessibility Scanner:

• Added error handling in the AccessibilityScanner class in src/tools/accessiblity-utils/scanner.ts to prevent scanning with local URLs when USE_OWN_LOCAL_BINARY_PROCESS is enabled, throwing an error with a clear message.
