feat: add streaming-widget package for Superfluid streaming flows on Celo and Base

[Copilot]

Implements packages/streaming-widget — a new GoodWidget for Superfluid CFA streams, GDA pool memberships, and Super Token balances, backed by @goodsdks/streaming-sdk@1.0.0.

Package structure

Follows the citizen-claim-widget pattern exactly: widgetRuntimeContract.ts → adapter.ts → StreamingWidget.tsx → element.ts/register.ts + index.ts.

Adapter (useStreamingAdapter)

• Builds viem PublicClient/WalletClient from the EIP-1193 provider for Celo (42220) and Base (8453)
• Composes StreamingSDK + GdaSDK instances; auto-refreshes on wallet/chain change
• Manages independent loading/error/success state slices for streams, pools, balance, and SUP reserve
• Set-stream form with inline validation → createOrUpdateStream write lifecycle (idle → pending → success/error)
• Per-pool connect/disconnect write status keyed by pool address

Widget UI (3 tabs via WidgetTabs)

• Streams — directional filter (All / Incoming / Outgoing), create/update form (recipient + amount + time-unit period selector → computed flow rate preview), stream list cards with direction badge / flow rate / streamed-so-far / timestamp
• Pools — GDA pool membership list with per-pool connect/disconnect action and inline write-status badge
• Balances — Super Token balance card; SUP reserve section renders on Base only, shows an explicit disabled explanation on other chains
• WalletGate handles not-connected and wrong-chain states before any tab content renders

Usage

// React component
<StreamingWidget provider={eip1193Provider} environment="production" />

// Web component
import '@goodwidget/streaming-widget/register'
// <gw-streaming></gw-streaming>

Storybook + Playwright

• Stories: InjectedWallet, CustodialLocalFixture, NoWallet under Widgets/StreamingWidget
• 8 Playwright smoke tests covering: connect-wallet prompt, tab bar visibility, loading/error states (RPC blocked), tab navigation, and create-stream form toggle

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• add-skill.vercel.sh
  • Triggering command: /usr/local/bin/node node /home/REDACTED/.npm/_npx/ac0ed6aa23b37c1e/node_modules/.bin/skills add REDACTED -y (dns block)
• https://api.github.com/repos/GoodDollar/GoodSkills
  • Triggering command: /usr/local/bin/node node /home/REDACTED/.npm/_npx/ac0ed6aa23b37c1e/node_modules/.bin/skills add REDACTED -y (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
