@wdio/native-cdp-bridge

Shared Chrome DevTools Protocol (CDP) bridge for WebdriverIO native-app services. Provides the low-level pieces every CDP-attach service needs, so each service composes rather than re-implements:

• Connection — a single CDP WebSocket connection to one target (request/response correlation, timeouts, observation-only — never issues Page.navigate).
• DevTool — HTTP target discovery (/json, /json/version) with port-wait/retry.
• CdpBridge — single-target client: discover → pick a target (selectTarget, default first) → connect. Supports an origin/headers option for endpoints that enforce a WebSocket Origin check (e.g. React Native's Fusebox inspector-proxy).
• MultiTargetCdpBridge — multi-target client: one Connection per target, with switchTarget/listWindows/refresh/sendTo, backed by a TargetRegistry. Target classification is injected (classifyTarget) so renderer-specific schemes stay in the consuming service.

Consumers:

• @wdio/electrobun-service — MultiTargetCdpBridge (CEF on macOS / native WebView2 on Windows, one target per window; supplies the target classifier).
• @wdio/react-native-service — CdpBridge (single Hermes target via Metro's inspector-proxy; supplies a Hermes selectTarget + origin).
• @wdio/electron-service — migrating to CdpBridge (single-target).

Not a public/user-facing package — it's internal infrastructure for the service family.
