Improve tool update output and version display

Fixed two UX issues in tool update management:

1. Version Check Output:
   - Extract version numbers using regex (v1.2.3 pattern)
   - Show clean version instead of full banner output
   - Fallback to "installed" if version can't be parsed
   - Fixes noise from tool ASCII art banners

2. Update All Go Tools:
   - List all tools before confirmation prompt
   - Show which tools are installed vs will be skipped
   - Skip uninstalled tools during update loop
   - Report skipped count in final summary
   - Users can see exactly what will be updated

Changes:
- Added regex version extraction in check_tool_versions()
- Added tool list display in update_all_go_tools()
- Added skip logic for uninstalled tools
- Updated summary to show: Updated | Failed | Skipped
