feat: add Vultisig wallet

[realpaaao]

Adds an injected-only connector for Vultisig — open-source, self-custodial multi-chain wallet with no seed phrase (threshold signatures across the user's devices). Live since March 2024.

Opened per the ask-first rule: discussion #2691.

Shape (modeled on rabbyWallet / enkryptWallet):

• Extension-only: no WalletConnect, no qr/mobile paths (Vultisig has no WC support — deliberate, not an omission)
• Detection: namespace: 'vultisig.ethereum' — window.vultisig is our multi-chain container (no request()); the EIP-1193 provider lives at .ethereum, same object we announce via EIP-6963 (rdns: 'me.vultisig', verified in extension source). A flag: isn't usable since our EVM provider sets isMetaMask for window.ethereum compat and exposes no isVultisig.
• Files: connector + full-bleed square SVG icon (matching recent wallet icons), walletConnectors/index.ts exports, en_US.json extension steps (en-US only per repo convention), example wagmi config, docs custom-wallet-list entry, changeset (patch).

Download links: Chrome Web Store + Firefox AMO (both listings live and verified) + browserExtension fallback.

receipts

no runtime changes to existing connectors — additive wallet entry

• pnpm --recursive typecheck → all 7 projects pass
• pnpm --filter @rainbow-me/rainbowkit build → succeeds; icon inlined as data URI, me.vultisig present in dist chunk
• pnpm format:check (biome) → exit 0; biome lint → no new warnings
• pnpm test → identical pass/fail set to clean tree (pre-existing env failures only)

Exclude Vultisig from MetaMask detection

When the Vultisig extension is installed, its EVM provider is also exposed as the MetaMask-compatible window.ethereum with isMetaMask: true, so adding this connector without also excluding window.vultisig.ethereum from metaMaskWallet leaves dApps that include both wallets (including the updated example/default MetaMask setup) showing MetaMask as installed and routing MetaMask clicks into the Vultisig provider. Please update the MetaMask impersonation filter alongside this connector so Vultisig users only get the Vultisig option.

Useful? React with 👍 / 👎.

[realpaaao]

Good catch — addressed in f42b519. The Vultisig EVM provider ships a distinguishing flag in every released extension version (isVultiConnect: true, from the extension's original name), so the impersonation filter now excludes on ethereum.isVultiConnect || ethereum.isVultisig — the second flag is forward-compatible with the extension's rename to "Vultisig Extension". With this, machines with only Vultisig installed no longer show MetaMask as installed, and MetaMask clicks no longer route into the Vultisig provider.
