chore: bootstrap OpenGym as an LLM-ready repository template

[lev1nson]

Motivation

• Создать базовый, повторно используемый шаблон репозитория для проектов, где основная логика и процессы завязаны на LLM.
• Дать готовую структуру и рекомендации для быстрой настройки system/user промптов и процесса контроля качества.
• Предоставить минимальный набор служебных файлов и визуальный баннер для быстрого старта и дальнейшей кастомизации.

Description

• Добавлен оформленный README.md с баннером assets/opengym-banner.svg и инструкциями по быстрому старту и структуре репозитория.
• Добавлены ключевые документы: docs/LLM_GUIDE.md, docs/ROADMAP.md, CHANGELOG.md и CONTRIBUTING.md для описания стандартов работы с моделями и плана развития.
• Созданы шаблоны промптов в prompts/system.md и prompts/task-template.md для фиксации поведения модели и типовых задач.
• Добавлены файлы репо-гигиены: .gitignore, .editorconfig, LICENSE, и простая GitHub Actions workflow .github/workflows/docs-check.yml для проверки наличия обязательных документов.

Testing

• Локальная проверка существования обязательных файлов с помощью test -f README.md && test -f docs/LLM_GUIDE.md && test -f prompts/system.md прошла успешно.
• Набор созданных файлов сверен со списком ожидаемых путей и их содержимое просмотрено на соответствие шаблону.
• Добавлен минимальный workflow docs-check.yml для автоматической валидации наличия документации, который готов к запуску в CI.

📝 Walkthrough

Walkthrough

This pull request introduces the foundational template structure for an LLM project named OpenGym. It adds configuration files, a CI workflow for documentation validation, comprehensive documentation including guides and roadmaps, MIT licensing, and reusable prompt templates.

Changes

Cohort / File(s)	Summary
Configuration & Tooling .editorconfig, .gitignore	Editor configuration for consistent formatting (UTF-8, LF line endings, 2-space indentation, trailing whitespace trimming) and ignore patterns for OS, IDE, environment, and language-specific artifacts.
CI/CD Workflow .github/workflows/docs-check.yml	GitHub Actions workflow that validates the existence of three required documentation files (README.md, docs/LLM_GUIDE.md, prompts/system.md) on pull requests and pushes to main.
Project Documentation README.md, CONTRIBUTING.md, CHANGELOG.md, docs/LLM_GUIDE.md, docs/ROADMAP.md	Comprehensive documentation suite including project overview and quick-start guide, contributor guidelines in Russian, changelog tracking initial setup, LLM usage standards with quality evaluation criteria, and phased project roadmap from bootstrap through production.
Legal & Licensing LICENSE	MIT License with copyright notice for 2026 OpenGym contributors.
Prompt Templates prompts/system.md, prompts/task-template.md	Reusable prompt templates: a system prompt template defining assistant behavior and safety constraints, and a standardized task template with sections for context, task description, input data, constraints, and definition of done.

Poem

🐰 A template takes shape, all tidy and neat,
With docs and workflows, the scaffolding's sweet,
Prompts and guidelines in Russian so fine,
Configuration aligned, each file in line,
OpenGym blooms—let the LLM shine! ✨
