feat(cli): Add -p shortcut and improve create command help text

Implemented Kimi's feedback suggestions:

1. Added -p shortcut for --preset flag
   - Makes presets easier to use: -p quick, -p standard, -p comprehensive
   - Updated create arguments to include "-p" in flags tuple

2. Improved help text formatting
   - Simplified description to avoid excessive wrapping
   - Made examples more concise and scannable
   - Custom NoWrapFormatter for better readability
   - Reduced verbosity while maintaining clarity

Changes:
- arguments/create.py: Added "-p" to preset flags
- create_command.py: Updated epilog with NoWrapFormatter
- parsers/create_parser.py: Simplified description, override register()

User Impact:
- Faster preset usage: "skill-seekers create <src> -p quick"
- Cleaner help output
- Better UX for frequently-used preset flag
