The changes are purely additive, adding support for two new networks (BOB and Rootstock/Rootstock Testnet):

1. New image files: bob.png, rootstock.png, rootstock-native.png - static assets
2. image-icons.js: Added exports for BOB and ROOTSTOCK icons
3. customNetworks.tsx: Added chain IDs (BOB: 0xed88, ROOTSTOCK: 0x1e, ROOTSTOCK_TESTNET: 0x1f) and their image mappings

These changes:

• Don't modify any existing functionality
• Add new constants and mappings to existing data structures
• Are used by various UI components for network image display (confirmations, balance, trending tokens)

The risk is low because:

• No existing code paths are modified
• The new networks won't affect users unless they explicitly add them
• The changes follow the established pattern for adding network support

Selected tags:

• SmokeNetworkExpansion: Directly tests new network configurations and network additions
• SmokeWalletPlatform: Tests core wallet functionality including network switching which may use these new network definitions
