---

This PR introduces Infrastructure as Code (IaaS) support in Praktika as a proof of concept, enabling automated deployment and configuration of CI infrastructure components.

Key changes:

1. PoC for IaaS support in Praktika: Configure and deploy cloud CI infrastructure components (dedicated hosts, EC2 instances, ASGs, IAMProfile) via Python Praktika's objects

2. Improved Praktika CLI interface: Deploy infrastructure with praktika infrastructure --deploy --only COMPONENTS

3. Infrastructure configuration documentation: Added README about infrastructure configuration via Praktika

4. MacOS infrastructure setup: Basic configuration for MacOS metal hosts and EC2 instances for macOS tests

5. Smoke test: Added MacOS functional tests job to validate the infrastructure (deployed metal host, and ec2 ci runner)

This lays the groundwork for managing CI infrastructure declaratively through Praktika.

Pull request overview

Introduces a Praktika CI proof-of-concept for managing AWS-based CI infrastructure (Dedicated Hosts / EC2 / Image Builder / Launch Templates / ASGs) and adds a macOS smoke test job, along with CLI/Docs updates to deploy/shutdown infrastructure via praktika infrastructure.

Changes:

• Add new infrastructure components (DedicatedHost, EC2Instance, IAMInstanceProfile, ImageBuilder, LaunchTemplate, AutoScalingGroup) and integrate them into CloudInfrastructure.
• Extend Praktika CLI with an infrastructure subcommand supporting --deploy/--shutdown and --only.
• Add macOS smoke test job and wire it into PR workflow dependencies; update workflow log timestamping.
