Align shared-commands with template structure (#13)

* Align shared-commands with template structure

- Remove unused commands not in template:
  - add-spec-comment.sh
  - add-user-story-comment.sh
  - create-epic.sh
  - create-user-story-issue.sh
- Add missing template files:
  - .gitignore
  - lib/templates/spec-template.md
  - package.json (updated to match template exactly)
- Keep only template commands:
  - analyze-issue.sh
  - create-spec-issue.sh
  - roadmap.sh
