fix: upgrade opensecret SDK to 0.2.9 for streaming tool call passthrough

[AnthonyRonning]

Problem

Streaming chat completions with multiple tool calls fail with:

Stream error: API error: 0: Failed to parse chunk: invalid type: null, expected a string at line 1 column 230

This happens because the OpenAI streaming spec sends null for id, type, and function.name in subsequent tool_call delta chunks. The SDK (0.2.8) had these as required String fields.

Fix

Upgrades opensecret from 0.2.8 to 0.2.9 (SDK PR), which makes ChatCompletionChunk a transparent serde_json::Value wrapper for full JSON passthrough.

Testing

Verified against enclave.secretgpt.ai with glm-5:

Test	Result
Health check	Pass
List models	Pass
Non-streaming completion	Pass
Streaming completion	Pass
Single tool call (non-streaming)	Pass
Parallel tool calls (non-streaming)	Pass
Streaming multi-tool calls (previously broken)	Pass
