feat(workflow): add interactive init-guidelines wizard for project guidelines configuration

Add /workflow:init-guidelines command that interactively fills project-guidelines.json
based on project analysis from project-tech.json. Features:
- 5-round questionnaire covering coding style, naming, file structure, documentation,
  architecture, tech stack, performance, security, and quality rules
- Dynamic question generation based on detected language/framework/architecture
- Append/reset mode for existing guidelines
- Multi-select options with "Other" for custom input

Modify /workflow:init to ask user whether to run init-guidelines after initialization
when guidelines are empty (scaffold only).
