fix(quickjs): forward config for skills and PTC tools

[Luiz Eduardo Zappa (luizzappa)]

Summary

Fixes #553.

createCodeInterpreterMiddleware() had two places where the LangGraph runnable config was available but not forwarded:

• the skillsBackend setup path
• Programmatic Tool Calling from inside the QuickJS REPL, e.g. await tools.task(...)

In the first case, getCurrentTaskInput() fell back to AsyncLocalStorage, which breaks in browser/web environments where AsyncLocalStorage is unavailable or stubbed.

In the second case, bridged tools were invoked without graph runtime config, which breaks tools that need current graph state, such as DeepAgents’ task tool.

Changes

• Pass config from the code interpreter tool handler into prepareSkillsForEval()
• Use getCurrentTaskInput(config) in the quickjs skills backend path
• Store the active eval tool config on ReplSession
• Forward that config to PTC tool invocations via t.invoke(rawInput, config)
• Add coverage proving a PTC tool invoked through tools.* receives the eval config

Why

This allows QuickJS skills and PTC tools to work in browser/web builds and preserves graph runtime context for tools called from inside the interpreter.

FWIW I think this might cause some issues with how we handle parallel eval calling. Its something we have to guard against at the emscripten boundary but if we make enhancements there this becomes problematic. We'll probably be addressing sometime soon so I'll try to keep this top of mind

Hello! Any blockers to merging this? I just hit this gap when trying to add tools to PTC that have different behavior based on the runtime context.
