Summary: Leah adds step-by-step workflow orchestration

Why It Matters: The product is moving from a tool that helps individuals to a system that manages entire business processes across different departments.

What Changed:

• Added a new "How Leah works" section showing a 6-step vendor approval workflow.
• Added a comparison table positioning Leah against "Functional SaaS" and "AI Assistants."
• Updated product descriptions to focus on "enterprise orchestration" rather than just "domain-specific agents."
• Changed "Contextual Data" to "Domain Expertise" in the features list, emphasizing faster time-to-value.
• Renamed navigation links to include the product name (e.g., "Leah Legal," "Leah Finance").
