[FEAT] Support mighty.standards storage and versioning in get_standard()

[akselthomsen]

Feature Request

Description

Update get_standard() and related functions to support the new mighty.standards storage solution and versioning scheme.

Proposed Solution

• Update get_standard() to retrieve components from the mighty.standards GitHub repo.
• Support multiple standard libraries in prioritized order.
• Add fallback to the latest tag of mighty.standards when no library is defined, with appropriate messaging or user prompt.

Use Case

Users need get_standard() to seamlessly fetch components from the versioned mighty.standards library.

Additional Context

See ADR-001: mighty.component integration and Versioning decisions.

Impact

Core integration point between mighty.component and the new standard library.
