Release v0.14.9

Fixed

• Broad questions about Cratis itself, such as "What is Cratis good at?", now always bring the documentation's overview pages (the home page, Why Cratis and the Cratis stack) to the answer instead of unrelated pages (#125)
• Short "what is Cratis" answers keep the overview's defining terms, such as event sourcing, instead of paraphrasing them away (#122)
• An answer that writes Anthropic's prompt cache is now charged its real cost against the daily spending budget instead of a much larger reservation, so the budget no longer runs out early; unknown or inconsistent usage still keeps the full reservation, and every rejected settlement is logged with its reason (#126)
