fix: remove noisy console.warn logs from NativeToolCallParser (#11264)

Remove two console.warn messages that fire excessively when loading tasks
from history:
- 'Attempting to finalize unknown tool call' in finalizeStreamingToolCall()
- 'Received chunk for unknown tool call' in processStreamingChunk()

The defensive null-return behavior is preserved; only the log output is removed.
