🧠 feat: Configurable Reasoning Replay for Custom Endpoints (#13921)
* 🧠 feat: Configurable Reasoning Replay for Custom Endpoints

Adds customParams.includeReasoningContent so OpenAI-compatible custom endpoints (e.g. Xiaomi MiMo, Kimi) can replay reasoning_content on tool-call turns natively, without impersonating the moonshot provider.

* 🔁 feat: Replay reasoning_content across turns for opted-in custom endpoints

Extends the DeepSeek reasoning-content format spoof to honor customParams.includeReasoningContent, so custom OpenAI-compatible endpoints (Xiaomi MiMo, Kimi) reconstruct reasoning_content from persisted history on later turns, matching DeepSeek thinking-mode parity. Adds shouldReplayReasoningContent predicate (tested) and surfaces the flag on the initialized agent.

* 🪢 refactor: Split within-run vs cross-turn reasoning replay flags

moonshot only replays reasoning_content within a run's tool calls, not across turns. Decouples the two: includeReasoningContent = within-run replay (exact moonshot parity), new includeReasoningHistory = cross-turn reconstruction from persisted history (implies includeReasoningContent, since reconstruction is a no-op without the within-run replay flag).

* 🩹 fix: Apply reasoning replay across all param-format branches

Move the within-run includeReasoningContent application out of the OpenAI-only branch in getOpenAIConfig to after the branch dispatch, so custom endpoints using anthropic/google defaultParamsEndpoint gateway modes also honor includeReasoningContent/includeReasoningHistory. Addresses Codex finding.

* chore: Update @librechat/agents to v3.2.46

* 🧽 refactor: De-spoof reasoning replay via explicit preserveReasoningContent

Now that @librechat/agents 3.2.46 exposes an explicit preserveReasoningContent option on formatAgentMessages, pass it directly instead of impersonating provider: deepseek. Behavior is unchanged (shouldReplayReasoningContent still gates DeepSeek + the custom includeReasoningHistory flag); also corrects the comment to reference includeReasoningHistory.

* 🌳 fix: Walk subagents in the reasoning-history replay gate

The gate only checked the primary agent and top-level handoff/parallel configs, so an opted-in custom endpoint used solely as a nested subagent had its persisted reasoning dropped on later turns. New exported anyAgentReplaysReasoningContent walks subagentAgentConfigs (cycle-safe, mirrors anyAgentHasCodeEnv); client.js uses it. Addresses Codex finding.
