Carry over #82973 and fix#81281 by preserving explicit cacheRetention for OpenAI-compatible completions providers that opt into prompt-cache-key support.
The change keeps explicit cacheRetention suppressed for OpenAI-compatible providers without compat.supportsPromptCacheKey, adds regression coverage for both paths, and updates prompt-caching docs for prompt_cache_key / prompt_cache_retention behavior.
Fixes#81281.
Supersedes #82973.

Fix runtime context placement so hidden runtime context is model-visible before the active user turn without persisting as a visible/session message.

Preserve replayability for direct Anthropic sessions whose stored assistant thinking blocks have empty or blank signatures after a newer user turn. Older invalid thinking-only assistant turns are replaced with the existing omitted-reasoning placeholder so the turn shape survives provider replay.
Also keep active tool-use continuations safe: when an assistant tool call is followed by tool results, preserve the latest assistant thinking block so signed-thinking providers can replay the current tool turn unchanged.
