Fix bin/dev --verbose option causing error

The --verbose flag was documented in bin/dev --help but not
implemented in the OptionParser, causing an error when used.

This fix:
- Adds verbose: false to the options hash
- Implements --verbose/-v flag parsing in OptionParser
- Updates all start() calls to use options[:verbose] instead of hardcoded false
- Adds RuboCop disable comment for increased AbcSize metric

Closes #1849
