refactor: rename hub-guide → code-guide, remove project-specific content

- Rename all references from hub-guide to code-guide
- Remove project-specific hub-guide skill (100% Asepharyana Hub specific)
- Genericize examples in monorepo, docker, ci-cd, engineering-principles skills
- Use generic service names (frontend, api, worker instead of hub, scraper)
- Use generic registry paths instead of ghcr.io/asepharyana/asepharyana-hub
- Remove project-specific deployment and infrastructure references
