Clarify internal execution pipeline in README

[FaikAijaz]

Summary

The current README provides a high-level overview of TemplateMark and AgreementMark, but it does not clearly describe the internal execution pipeline of the Template Engine.

In particular, the flow involving:

• Type validation
• TypeScript compilation
• Runtime evaluation using JavaScriptEvaluator
• AgreementMark generation

is not explicitly documented.

Proposed Improvement

Add a new "Execution Pipeline Overview" section to the README to clarify:

• The internal evaluation stages
• The role of TemplateMarkToJavaScriptCompiler
• The role of JavaScriptEvaluator
• The validation steps before and after generation

This would improve onboarding for contributors and tool developers.
