Add multiple LaTeX resume templates with template selection system

Created:
- jb2resume-modern.latex: Improved classic template with better spacing,
  modern typography, proper bullet points, and visual hierarchy
- awesome-cv.latex: Modern, vibrant template inspired by awesome-cv with
  accent colors and contemporary design

Updated Makefile:
- Add resume-modern target for building with improved template
- Add resume-awesome target for building with awesome-cv template
- Keep classic resume target for original jb2resume template
- Add help target showing all available commands and templates
- Improved documentation with template usage examples

Updated CLAUDE.md:
- Document all three templates with descriptions
- Add template selection guide with decision tree
- Provide recommendations for different company types
- Show example usage for each template

Template Usage:
  make resume FILE_NAME=path/to/resume           # Classic jb2resume
  make resume-modern FILE_NAME=path/to/resume    # Modern improved
  make resume-awesome FILE_NAME=path/to/resume   # Awesome-CV inspired

Rebuilt all existing resumes with modern template as default,
with awesome-cv versions available for comparison.

Benefits:
- Multiple visual styles to match company culture
- Better spacing and readability in modern template
- Professional appearance with subtle or bold styling options
- All templates ATS-compatible for automated screening
- Easy to test different visual presentations
