Description

Fix: merge filter tools with internal tools instead of replacing

Fixes #24237

When a filter function returns provider-native tools, process_chat_payload was overwriting the existing internal tools array instead of merging them. This caused internal tools to be silently dropped.

Changes:

Modified process_chat_payload to merge provider-native tools from filters with existing internal tools
If body["tools"] contains only provider-native entries, they are copied to provider_native_tool_addons and tools is popped, allowing resolution to proceed normally

Testing:

Verified that filter-returned tools are merged with existing internal tools
Verified that internal tools remain accessible when filters add provider-native tools
