Greptile Summary

Fixes three TypeScript compilation errors introduced by the gateway HTTP handler refactor (commit 2fd8264ab):

• Removes duplicate registerPluginHttpRoute import in extensions/googlechat/src/monitor.ts (TS2300)
• Removes stale registerHttpHandler() property from test mock in extensions/phone-control/index.test.ts — this method was removed from OpenClawPluginApi interface as part of the breaking change that deprecated api.registerHttpHandler() in favor of api.registerHttpRoute()
• Adds explicit return type Promise<ReturnType<typeof createResponse>> to sendRequest() in src/gateway/server-http.test-harness.ts to resolve non-portable inferred type error (TS2742)

All fixes are minimal, correct, and directly address the compilation failures blocking CI on all open PRs.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• All three changes are straightforward TypeScript compilation fixes with no behavioral changes. The fixes correctly align with the breaking changes from the gateway refactor commit, removing deprecated API references and fixing type inference issues. No logical errors, security concerns, or side effects.
• No files require special attention
