fix: update CLI argument parser test expectations for default options

The CLI tests were failing because they expected empty options `{}` but
now receive a full options object with default values due to CLI improvements.

Updated both failing test cases in argument-parser.test.ts:
- 'should handle empty arguments and return help context'
- 'should handle help flags without process.exit'

Both tests now correctly expect the default options object:
- autoConfig: false
- autoSample: false
- continueOnError: false
- dryRun: false
- enableCaching: undefined
- enableHashing: true
- fallbackOnError: true
- force: false
- forceIndividual: false
- forceSequential: false
- includeEnvironment: true
- progressiveReporting: false
- quiet: false
- showProgress: true
- streamingOptimizations: false
- verbose: false

All CLI argument parser tests now pass (55/55).
