feat: add --githubMode and --userPrompt as boolean CLI options

[bhouston]

Description

This PR adds --githubMode and --userPrompt as boolean command line options that override any config settings or defaults. These CLI options are required for our GitHub Action integration to work properly.

Changes Made

1. Added githubMode to the SharedOptions type and sharedOptions object in options.ts
2. Added userPrompt as an alias for enableUserPrompt in options.ts
3. Updated the default command handler to properly use these CLI options to override config values:
   • Now checking for argv.githubMode before falling back to config.githubMode
   • Now checking for argv.userPrompt before falling back to argv.enableUserPrompt
4. Updated README.md to document the new CLI options

Testing

• All existing tests pass
• Manually verified that the CLI options work as expected
