Add Wrapped 0G (W0G) on Ethereum, Base and Robinhood Chain

[udhaykumarbala]

Adds metadata and icons for Wrapped 0G (W0G), the official Chainlink CCIP issued representation of the 0G token, on three chains whose folders already exist in this repo.

CAIP-19 asset ID	Name	Symbol	Decimals
eip155:1/erc20:0x4C1Dab3Be86347977F3DfC4b9688224ef2272939	Wrapped 0G	W0G	18
eip155:8453/erc20:0x23cd099eB438CcA50349EE2BC809196b1ae00861	Wrapped 0G	W0G	18
eip155:4663/erc20:0x32003CC8357938bCF615c1222a349c58f2B30698	Wrapped 0G	W0G	18

On-chain verification

name(), symbol() and decimals() were read over each chain's public RPC: all three return Wrapped 0G, W0G, 18. Supplies are in the 530k to 540k range on each chain, consistent with a single bridged supply.

Icon

Reuses the W0G SVG already in this repo at icons/eip155:16661/erc20:0x1Cd0690fF9a693f5EF2dD976660a8dAFc81A109c.svg (the 0G Mainnet W0G added in #1886), so the token renders identically on every chain.

Relationship to other 0G assets

• The 0G Mainnet W0G (eip155:16661) is already present and untouched.
• The older LayerZero OFT "0G" at 0x4B948d64dE1F71fCd12fB586f4c776421a35b3eE (Ethereum and BNB Chain) is a different contract and is not part of this PR.
• Add Ascend Staked 0G (a0G) token icon and metadata for 0G Mainnet (eip155:16661) #1969 (open) adds Ascend Staked 0G (a0G) on 0G Mainnet; independent of this change.

Checklist

• Verified source on the canonical explorer for each chain
• ERC-20, not ERC-721 or ERC-1155
• Only permitted fields (name, symbol, decimals, erc20, logo)
• Additive only, six new files, no existing file touched
• yarn test passes; npm run asset:verify -- --caip <id> passes for all three assets

Note

Low Risk
Additive asset metadata and static icons only; no application logic, auth, or existing entries changed.

Overview
Registers Wrapped 0G (W0G) as a new ERC-20 asset on three EVM chains by adding CAIP-19 metadata (name, symbol, decimals, erc20, logo) and matching 512×512 SVG icons for each contract.

Deployments covered: Ethereum (eip155:1), Base (eip155:8453), and Robinhood Chain (eip155:4663). Icons reuse the same W0G artwork as the existing 0G Mainnet entry so W0G displays consistently across chains. No existing files are modified—six new files only.
