Pull Request Overview

This PR optimizes code by eliminating unnecessary list allocations and modernizes F# syntax by migrating from explicit lambda expressions to the more concise underscore property access syntax.

• Replaced array/list creation with sequence operations to avoid intermediate allocations
• Migrated from fun x -> x.Property syntax to _.Property syntax throughout the codebase
• Updated option handling to use ValueOption where appropriate for better performance
