fix: Fail on unsupported architectures

[spetrosi]

Enhancement: This role supports the x86_64 architecture only

Summary by Sourcery

Enforce x86_64-only support by failing on other architectures, update documentation accordingly, and skip tests for unsupported architectures

Enhancements:

• Add fail task in main role to abort on non-x86_64 architectures
• Update README to declare x86_64 as the only supported architecture

Documentation:

• Document x86_64-only restriction in the README

Tests:

• Introduce skip_unsupported_archs.yml to halt tests on unsupported architectures
• Include skip logic in all test playbooks to bypass non-x86_64 hosts

Reviewer's Guide

Enforce x86_64-only support by failing early on unsupported architectures in the main role, centralizing skip logic for test suites, updating all tests to include this skip, and documenting the constraint in the README.
