feat: Add Auggie CLI (Augment Code) Integration (#520)

* feat: add Augment Code IDE support with multi-location installation options

- Add Augment Code to supported IDE list in installer CLI and interactive prompts
- Configure multi-location setup for Augment Code commands:
  - User Commands: ~/.augment/commands/bmad/ (global, user-wide)
  - Workspace Commands: ./.augment/commands/bmad/ (project-specific, team-shared)
- Update IDE configuration with proper location handling and tilde expansion
- Add interactive prompt for users to select installation locations
- Update documentation in bmad-kb.md to include Augment Code in supported IDEs
- Implement setupAugmentCode method with location selection and file installation

This enables BMAD Method integration with Augment Code's custom command system,
allowing users to access BMad agents via /agent-name slash commands in both
global and project-specific contexts.

* Added options to choose the rule locations

* Update instruction to match with namespace for commands

* Update instruction to match with namespace for commands

* Renamed Augment Code to Auggie CLI (Augment Code)
