Description
Fix tool selection not being properly reset when switching models in chat (fixes#14157)
Fixed
When switching to a model with configured tools, only that model's tools are now selected (removed unnecessary new Set wrapping)
When switching to a model with no configured tools and no user defaults, selectedToolIds is now cleared entirely instead of preserving tools from the previous model
Testing Evidence
Setup: Created 2 tools (Weather Tool, Calculator Tool) and 3 model presets:
Test Model X — configured with Weather Tool
Test Model Y — configured with Calculator Tool
Test Model Z — configured with NO tools
Test 1 — Select Model X: Wrench icon shows "1" (Weather Tool) ✅ Test 2 — Switch to Model Y: Wrench shows "1" (Calculator Tool only, Weather cleared) ✅ Test 3 — Switch to Model Z: Wrench icon gone entirely (all tools cleared) ✅
