docs: reorganize AI Copilot documentation structure

- Add README.md with documentation overview and structure guide
- Move implemented designs to docs/gns3-copilot/implemented/:
  - chat-api.md (from ai-chat-api-design.md)
  - llm-model-configs.md (from llm-model-configs-api.md)
  - command-security.md
  - context-window-management.md
- Add Jinja2 configuration template system design documents:
  - jinja2-config-templates-system.md
  - config-templates-implementation-guide.md
  - ai-prompting-for-config-templates.md
- Remove obsolete documents (acl-web-ui, Chinese RBAC doc)

This reorganization makes it clearer which features are implemented
vs planned, following the established documentation structure.
