Integrate outputOptions into embedding option sets

Update auditOpts and verifyCommitOptions to properly use the new
outputOptions architecture methods instead of directly managing
the format flag.

- Call outputOptions.AddFlags() in both auditOpts and verifyCommitOptions
- Call outputOptions.Validate() in both Validate() methods
- Remove direct format flag registration from both files
- Remove manual format initialization (now handled by AddFlags())

This completes the refactoring to follow the established command
architecture pattern where option sets manage their own flags and
validation through AddFlags() and Validate() methods.
