Prompt results now carry model config

8.5.0

Minor Changes

• #4329 5baf90a Thanks @jurajmajerik! - Prompts.get() results now include config, the JSON object of model parameters or agent configuration stored with the prompt version in PostHog prompt management (null when the version has none). Config is carried through the client-side cache and the stale-cache fallback, and each result gets its own copy so mutating result.config cannot pollute later cache hits. The hardcoded fallback string has no config, so use defensive access like (result.config ?? {}).temperature. (2026-07-30)
