feat: add robinhood chain (4663)

[matheus1lva]

Summary

Adds Robinhood Chain (chain ID 4663) as a supported indexing chain, plus a manual entry
for its spUSDG/USDG Morpho looper vault.

How to review

• packages/lib/chains.ts / packages/web/chains.ts: new robinhood chain def, RPC and
  block explorer URLs, multicall3 address.
• packages/lib/multicall3.ts: activation block wired for the new chain.
• packages/ingest/prices.ts: added to the price-service chain-name map.
• config/manuals.yaml: manual vault entry for 0xC7d60aBfa6f4D79C2C42Bf84A54795bD8c586957.
• .env.example: new HTTP_ARCHIVE_4663 / HTTP_FULLNODE_4663 vars.

Test plan

• Manual, local integration:
  1. In .env, set HTTP_ARCHIVE_4663 and HTTP_FULLNODE_4663
     (public RPC: https://rpc.mainnet.chain.robinhood.com).
  2. make dev, wait for redis/postgres/ingest/web to come up.
  3. In the terminal pane: ingest → fanout abis. Run it twice if the first pass
     only seeds manuals.
  4. Check the vault landed:
     select chain_id, address, label from thing where chain_id = 4663;
     expect 0xC7d60aBfa6f4D79C2C42Bf84A54795bD8c586957 with label vault.
  5. Check snapshot/evmlog rows exist for chain 4663 and evmlog_strides covers blocks
     from inceptBlock 3362381 onward.
  6. Query http://localhost:3001/api/gql for the vault on chainId 4663 and confirm
     name spUSDG/USDG Morpho Looper, asset 0x5fc5…d168, decimals 6.
  7. Prices: with USE_PRICE_SERVICE on, confirm no "unavailable price" loop in ingest
     logs for chain 4663 (chain-name map entry robinhood).
• Automated (when applicable): not run.

Risk / impact

Additive only, no changes to existing chains. Rollback: remove robinhood from
config/chains.yaml.

The chain definition itself checks out against the live chain: chain id, multicall3 predeploy, explorer, vault creation block, incept timestamp, asset, decimals and name all match.

Issues

• Manual entry contradicts the on-chain contract (high) — the vault is a Yearn TokenizedStrategy (apiVersion 3.0.4, share symbol ysUSDG) but is recorded as non-Yearn, non-v3 with no apiVersion, so none of the yearn/3 hooks (reports, fees, performance) run for it and it is absent from every v3- or yearn-filtered API query, which is how most consumers find vaults. config/manuals.yaml:213
  Done when: the thing's defaults match the contract, and vaults(chainId: 4663, v3: true) and vaults(chainId: 4663, yearn: true) both return it.

• Price service does not know the new chain name (high, handled in yearn-prices) — every price lookup tested for chain 4663 fails with a server error, in both the exact and batch routes, the same response a made-up chain name gets. Until that lands the vault gets no USD TVL, and because the batch queue is shared across chains, one Robinhood coin in a flush window fails the whole batchHistorical request and pushes every other chain's coins in that window to per-coin fallback calls. The fix is being tracked in the yearn-prices project, not here; this PR just needs to keep 4663 mapped to the name that service ends up using. packages/ingest/prices.ts:208
  Done when: the historical price route for robinhood:0x5fc5…d168 returns 200 or 404 rather than 500, and a mixed batch containing a Robinhood coin returns 200. Test plan step 7 should be re-run once that is true.
