Eric Allam 14958009b8 docs(ai-chat): add prompt caching guide (#3951)
## Summary

New `/ai-chat/prompt-caching` guide covering how to cache a chat agent's
prompt prefix with Anthropic prompt caching: the system prompt, the
conversation history (a `prepareMessages` breakpoint), and how caching
interacts with compaction. It also shows how to verify cache hits via
usage and the dashboard, the prefix-stability footguns, and an "Other
providers" section (OpenAI and Google cache automatically; Amazon
Bedrock uses `cachePoint` through `systemProviderOptions`).

Registered under Features in the AI Agents nav, next to Compaction.
