Implement dynamic provider alias mapping

[ephur]

Support dynamic remapping of Terraform provider aliases passed to submodules. Should work for any provider (not just AWS). Investigate patterns for passing provider blocks via variables or configuration.

🤖 Initial triage (AI-generated):

This enhancement touches Terraform core architecture. The goal is to allow submodules to dynamically accept provider aliases. Based on the project layout, this likely involves modifying how ModuleBuilder or equivalent logic constructs providers via templated injection.

⚙️ Suggested path:

• Accept a provider alias map in the CLI or config
• Pass through the terraform render context
• Ensure module provider = aws.foo syntax resolves based on input map

🧪 Needs validation of edge cases like fallback/default behavior for optional providers.
