[codex] Remove local runtime websocket connector

[EYHN]

Summary

• Render the local environment inventory directly into the local agent system prompt so sandbox mount details are available at startup.
• Remove the unused WebSocket environment connector path and keep LocalRuntimeConnector as an in-process facade for macOS and embedded VM tool execution.
• Drop the WebSocket wire protocol, request dispatch, streaming RPC handlers, ping/reconnect logic, and related bridge capability shim.

Validation

• xcrun swiftc -parse macos/OpenBridge/Agent/LocalRuntime/LocalRuntimeConnector.swift macos/OpenBridge/Agent/LocalRuntime/LocalRuntimeConnectorHandlers.swift macos/OpenBridge/Agent/LocalRuntime/LocalRuntimeConnectorTypes.swift macos/OpenBridge/Agent/LocalRuntime/OpenBridgeSystemPromptBuilder.swift macos/OpenBridge/Agent/LocalRuntime/LocalAgentSession.swift macos/OpenBridge/Agent/AgentSessionManager.swift
• Pre-commit SwiftFormat/SwiftLint passed for the staged Swift files.
• Full BUILD_CONFIGURATION=UnsignedDebug bash DevKit/Scripts/workspace_build_debug.sh could not complete because this worktree is missing kwwk/Package.swift, so Xcode package resolution fails before compilation.
