default tool type to "function" (sometimes APIs omit this from deltas)

Walkthrough

In the processChatStream function within the OpenAI chat backend, a ToolCall struct that is appended to toolCallsInProgress is now initialized with the Type field explicitly set to "function" rather than being initialized as an empty struct. This ensures newly created entries have a default type value established at initialization time.

• Single-line change in one function with straightforward struct field initialization
• No logic, control-flow, or exported signature modifications
• No broader API surface changes affecting other components

167-189: Defaulting ToolCall.Type to "function" is a clean, targeted fix

Initializing new ToolCall entries with Type: "function" aligns with the struct’s documented default and ensures Type is non‑empty when the upstream delta omits it, while still allowing explicit tcDelta.Type values to override it. If you already have (or later add) a shared constant for the "function" type, consider using it here to keep things DRY, but the current change is correct and safe as-is.

Timestamp: 2025-10-15T03:21:02.229Z
Learning: In Wave Terminal's AI tool definitions (pkg/aiusechat/tools_*.go), the Description field should not mention approval requirements even when ToolApproval returns ApprovalNeedsApproval. This prevents the LLM from asking users for approval before calling the tool, avoiding redundant double-approval prompts since the runtime will enforce approval anyway.
