feat: enable Robinhood chain in production

[kaladinlight]

Description

Turns on Robinhood Chain (EVM 4663) in production by flipping VITE_FEATURE_ROBINHOOD to true in .env and dropping the now-redundant .env.development override.

All the underlying support landed in #12497 (chain adapter, CAIP constants, base asset, hdwallet coinbase/ledger/keepkey/trezor/native/phantom/vultisig/gridplus/walletconnect, CSP headers, RPC/viem clients, asset generation, and swapper support in Relay/Across/deBridge/ButterSwap/Bebop/0x) — this PR only lifts the flag.

Also moves the flag out of the # Dev tools block in .env and up with the other chain flags, where it belongs.

Risk

Low. The change is a single feature-flag flip; no code paths change. VITE_FEATURE_ROBINHOOD still defaults to false in src/config.ts, and every consumer (src/constants/chains.ts, PluginProvider) already gates on it, so the blast radius is limited to Robinhood being present in chain/asset lists and swapper routes.

What protocols, transaction types, wallets or contract interactions might be affected by this PR?

Robinhood Chain sends/receives (native ETH and ERC20s), and swaps routing through Robinhood on the swappers that already list it: Relay, Across, deBridge, ButterSwap, Bebop and 0x. Wallets supporting EVM 4663: Native, Ledger, KeepKey, Trezor, Coinbase, Phantom, Vultisig, GridPlus, WalletConnect v2, MetaMask multichain.

Testing

Engineering

• develop already runs with the flag on locally (it was true in .env.development), so this is effectively promoting the dev behavior to all environments.
• Verify the Robinhood network appears in the asset/chain selectors and that VITE_ROBINHOOD_NODE_URL (https://rpc.mainnet.chain.robinhood.com) resolves in the preview env.
• Confirm balances load for an account with funds on Robinhood, and that a quote can be fetched for a Robinhood asset.

Operations

• 🏁 My feature is behind a flag and doesn't require operations testing (yet)

Functional testing in the preview env:

1. Connect a wallet, confirm Robinhood shows up under networks / chain filters.
2. Check that the Robinhood ETH balance and market data render on the dashboard and asset page.
3. Get a trade quote into and out of Robinhood (Relay is the primary route) and confirm the explorer links point at robinhoodchain.blockscout.com.

Review limit reached

@kaladinlight, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 25 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

I’m a rabbit flipping flags with care,
Robinhood now blooms in the air.
Development stays clean and bright,
One true setting guides the flight.
Hop, hop—configuration right!

Keep the feature flag declaration in dotenv-linter order.

dotenv-linter reports that VITE_FEATURE_ROBINHOOD should precede VITE_FEATURE_RUNEPOOL. Move this declaration before VITE_FEATURE_RUNEPOOL to keep the environment file lint-clean.
