[Feature Request]: Add tool call chunk count to ActivityIndicator processing status

[sorrycc]

Problem

When AI is processing, the ActivityIndicator.tsx currently shows token count during streaming:

Processing... (Esc to cancel, ↓ 123 tokens)

However, there are two issues:

1. No visibility into how many tool call chunks have been received during streaming
2. Token count only includes text-delta and reasoning-delta chunks, missing tokens from tool-call chunks

Solution

Extend the ActivityIndicator to display tool call chunk counts and include tool-call tokens in the total count:

Processing... (Esc to cancel, ↓ 123 tokens, 🔧 3 tools)

Implementation approach:

1. Track tool call chunks in store.ts: Add a processingToolCalls counter similar to processingTokens

2. Update chunk handler in store.ts: Currently only counts text/reasoning tokens:

if (chunk.type === 'text-delta' || chunk.type === 'reasoning-delta') {
  const tokenCount = countTokens(chunk.delta);
  set({ processingTokens: get().processingTokens + tokenCount });
}

Should be extended to also count tool-call tokens:

if (chunk.type === 'text-delta' || chunk.type === 'reasoning-delta') {
  const tokenCount = countTokens(chunk.delta);
  set({ processingTokens: get().processingTokens + tokenCount });
} else if (chunk.type === 'tool-call') {
  const tokenCount = countTokens(JSON.stringify(chunk));
  set({ 
    processingTokens: get().processingTokens + tokenCount,
    processingToolCalls: get().processingToolCalls + 1 
  });
}

3. Display in ActivityIndicator: Update the statusText in ActivityIndicator.tsx to include the tool call count

Reference files:

• src/ui/ActivityIndicator.tsx - UI component to update
• src/ui/store.ts - Already tracks processingTokens, needs processingToolCalls
• src/loop.ts - Shows how tool-call chunks are emitted via onChunk
• src/nodeBridge.ts - Bridge layer for chunk events

Alternatives

Could also display this in the /status command output, but real-time feedback during processing is more valuable.

Importance

Would make my life easier - provides better visibility into agent progress during complex multi-tool operations.

要不要考虑流式输出 现在总结类的 感觉需要等待特别久
