Add GitHub Actions workflow for Bot Docker build and push

[Copilot]

Adds CI/CD automation for building and pushing the Bot's Docker container to Yandex Cloud Registry using a standalone GitHub Actions workflow designed specifically for the Python Bot application.

Changes

• Standalone Workflow (.github/workflows/bot-docker-build-push.yml)

  • Native GitHub Actions workflow using Docker ecosystem actions
  • Uses docker/build-push-action@v5 for efficient Docker builds
  • Uses docker/setup-buildx-action@v3 for advanced build features
  • Uses docker/metadata-action@v5 for automatic tag generation
  • Implements GitHub Actions cache for Docker layers (faster builds)
  • Triggers on push to main/develop branches and bot-v* tags
  • Uses existing YC_REGISTRY_ID and YC_SERVICE_ACCOUNT_KEY secrets
  • Builds from Bot/Dockerfile and pushes to cr.yandex/{registry_id}/meethub-bot

• Security

  • Added explicit permissions: contents: read for security best practices
  • Conditional push based on secrets availability

• Tagging Strategy

  • latest tag for default branch
  • Branch name tags for feature branches
  • Tag name for release tags
  • SHA-prefixed tags for traceability

The Bot workflow is completely independent and uses no C# or .NET tooling, making it appropriate for the Python-based Bot application.

Original prompt

On Bot, add github actions for building bot making docker container and pushing it to registry. example you could see in existing github actions and Nuke build

just create new github actions. do not use nuke it is for c#. bot is in python.

Done! I've replaced the Nuke-based approach with a standalone GitHub Actions workflow specifically for the Python Bot. The new workflow uses native Docker actions and doesn't depend on any C# tooling.

Key changes in commit 6041d06:

• Uses docker/build-push-action@v5 for building and pushing
• Implements Docker Buildx with GitHub Actions caching
• Automatic tag generation for multiple strategies (latest, branch, tag, SHA)
• No dependencies on Nuke or .NET

The workflow triggers on push to main/develop branches and bot-v* tags, building from Bot/Dockerfile and pushing to cr.yandex/{registry_id}/meethub-bot.
