feat: full-recipe unit conversion

[tmlmt]

Description

Added a new unit conversion feature that allows converting an entire recipe to a specific unit system. This includes a comprehensive implementation with three conversion methods: "keep", "replace", and "remove" to control how existing equivalents are handled during conversion.

The documentation has been reorganized to separate unit conversion guidance from unit definitions. The new convertTo() method on the Recipe class enables full-recipe unit conversion between metric, US, UK, and JP measurement systems.

Related Issue: N/A

Type of change

• New feature (non-breaking change which adds functionality)
• Documentation change (improvement to the Vitepress documentation or playground)

How Has This Been Tested?

• Comprehensive unit tests for the convertTo() method covering various scenarios
• Tests for handling different unit types, ranges, and alternatives
• Tests for all three conversion methods: "keep", "replace", and "remove"
• Integration with the playground UI for interactive testing
