🐛 Fix Tool Call Display: Show Names Instead of Parameters

This PR fixes a UI bug where tool calls with parameters displayed confusing parameter information instead of clear tool names for unknown/unrecognized tools.

🚨 Problem Solved

Confusing Tool Display: Unknown tools with parameters showed parameter details instead of tool names, making it hard for users to understand what Goose was doing:

✨ What's Fixed

🔧 Clean Fallback Logic

• Unknown tools now return null → triggers proper tool name fallback
• Consistent display for all unrecognized tools
• Parameter details still available in expandable "Tool Details" section

🎨 Enhanced Tool Name Display

• Truncation for long names (50 character limit with ellipsis)
• Consistent formatting using existing snakeToTitleCase utility
• Shared truncation logic eliminates code duplication

🚀 Key Improvements

✅ Better User Experience

// Before: Confusing parameter list
"support_type, start_date, end_date, category"

// After: Clear, descriptive tool name  
"Retrieve Support Tickets"

✅ Handles All Tool Types

• Known tools: Custom descriptions (unchanged)
• Unknown tools: Formatted tool names (fixed)
• Long tool names: Properly truncated (enhanced)

🎁 User Experience Enhancements

• Clear tool identification - Users can immediately see what tool is running
• Consistent display format - All tools follow same naming pattern
• Parameter details preserved - Still accessible via expandable sections
• Cleaner UI - No more confusing parameter lists in tool headers

🔧 Technical Implementation

Core Changes

• Simplified default case - Returns null to trigger fallback
• Extracted truncate helper - Shared between functions for consistency
• Enhanced fallback logic - Formats and truncates tool names properly

// Enhanced fallback with shared truncation
const toolName = toolCall.name.substring(toolCall.name.lastIndexOf('__') + 2);
return truncate(snakeToTitleCase(toolName));

🎨 Examples of Fixed Display

MCP Extension Tools

❌ Before: "start_date, end_date, category"
✅ After:  "Retrieve Support Tickets"

❌ Before: "issueKey, summary, description"  
✅ After:  "Create Issue"

❌ Before: "environment, orderId, country"
✅ After:  "Get Order Transaction Details..."

📊 Impact

Bug: Tool names missing for unknown tools → Fixed: All tools show clear names
Code Quality: Duplicated truncation logic → Improved: Shared helper function
UX: Confusing parameter lists → Enhanced: Clear, truncated tool names
Maintainability: Scattered logic → Consolidated: Single source of truth

✅ Testing

• ✅ TypeScript compilation passes
• ✅ ESLint checks pass
• ✅ No breaking changes to existing functionality
• ✅ Known tools still show custom descriptions
• ✅ Unknown tools now show formatted names
• ✅ Long tool names properly truncated

🔧 Files Changed

• src/components/ToolCallWithResponse.tsx - Fixed fallback logic and added shared truncation
