Make max tool-calling round trips configurable via AppConfig and Advanced Settings

[haiphucnguyen]

Summary

The maximum number of tool-calling round trips is currently hardcoded to 10 in AiServiceBuilder.kt:

builder.toolProvider(toolProvider).maxToolCallingRoundTrips(10)

This should be user-configurable so that power users running agentic/multi-step workflows can raise the limit, while conservative users can lower it to reduce cost and latency.

Changes Required

1. AppConfig.kt — add config field
   Add to the models config section:

val maxToolCallingRoundTrips: Int = 10

2. AiServiceBuilder.kt — read from config

// Before:
builder.toolProvider(toolProvider).maxToolCallingRoundTrips(10)

// After:
builder.toolProvider(toolProvider)
.maxToolCallingRoundTrips(AppConfig.models.maxToolCallingRoundTrips)

3. AdvancedSettingsSection.kt — add UI control
   Add a numeric input in the Advanced Settings panel:
   Label: Max tool-calling round trips
   Description: Maximum number of tool calls the AI can make in a single response. Higher values allow more complex agent tasks but increase latency and cost.

Default: 10
Range: 1 – 50
