* fix(sse): compact Responses multi-turn images before context hard-reject (#8560)
Codex Desktop sessions near the 372k input cap were rejected on the second
inline image because compressContext no-op'd on Responses input[] and never
pruned older vision turns. Adapt via bodyAdapter, prune older images while
keeping the latest, and run last-resort compaction before the budget check.
* docs(env): document CONTEXT_KEEP_LATEST_IMAGES for #8560
Keep check:env-doc-sync green after the context image-pruning override.
