feat(openviking): add full recall prefetch policy
Salvage of PR #48927 by @ehz0ah, which consolidates OpenViking recall work from #41706 (@huangxun375-stack), #33260, #49975, and #32444. Replaces stale background post-turn prefetch warming with synchronous current-query recall. The old queue_prefetch warmed the PREVIOUS user message while turn-start recall consumed the CURRENT one, so injected context was always about the wrong topic. Changes: - prefetch() now does session-aware /api/v1/search/search with the current query, falls back to /api/v1/search/find on failure - Contract-safe payloads: limit, score_threshold, context_type, session_id — no top_k, no search-body mode, no target_uri - L2 content reads for items with level=2 or empty abstracts, capped at full_read_limit (default 2) - Local ranking (score + query-token overlap + leaf boost), dedup, score threshold, and injected-char budget - queue_prefetch() is now a no-op (background warming removed) - Additive batched viking_read: uris param accepts up to 3 URIs - Per-request timeout support on _VikingClient.get/post/delete - Removes stale _prefetch_result/_prefetch_thread/_prefetch_generation state and _invalidate_prefetch_state() - Strengthened system_prompt_block guidance Salvage follow-up fixes: - Expose all 8 recall config knobs in get_config_schema() (PR #48927 had removed them; #41706 correctly exposed them). Env vars remain as internal mechanism but are now visible in setup wizard. - Lower default timeout 8s→4s, request_timeout 6s→3s, full_read_limit 3→2 to reduce per-turn blocking latency.
