Add Aider integration for beads issue tracking

Implements GH#206 and bd-3djj: Add support for Aider AI pair programming
tool with beads issue tracking.

Changes:
- Added cmd/bd/setup/aider.go with InstallAider, CheckAider, RemoveAider
- Created .aider.conf.yml template with bd workflow instructions
- Added .aider/README.md template with quick reference
- Updated cmd/bd/setup.go to include aider subcommand
- Fixed cmd/bd/main.go to allow setup subcommands without database by
  checking parent command name
- Added comprehensive docs/AIDER_INTEGRATION.md documentation

Key differences from Claude/Cursor integration:
- Aider requires explicit command execution via /run
- AI suggests bd commands rather than running autonomously
- Documentation emphasizes human-in-the-loop workflow
- Config instructs AI to always suggest, never execute

Usage:
  bd setup aider          # Install integration
  bd setup aider --check  # Verify installation
  bd setup aider --remove # Remove integration
