* feat(standard-tests): make test suite framework-agnostic and publish as public package
Move @langchain/sandbox-standard-tests from internal/ to libs/ for
publishing. The test suite no longer hard-depends on Vitest — test-runner
primitives (describe, it, expect, beforeAll, afterAll) are supplied via
a `runner` config property, letting consumers use any framework.
A convenience sub-export at @langchain/sandbox-standard-tests/vitest
pre-fills the runner with Vitest primitives for zero-config usage.

fix(deepagents): unwrap responseFormat strategy types so structuredResponse is correctly typed ( #222 )
...
* fix(deepagents): unwrap responseFormat strategy types so structuredResponse is correctly typed
Previously, passing responseFormat to createDeepAgent would leak the
strategy wrapper type (e.g. ToolStrategy<{ city: string }>) into the
agent's structuredResponse property instead of the inner parsed type
({ city: string }). This adds an InferStructuredResponse utility type
that extracts T from ToolStrategy<T> / ProviderStrategy<T>, and resolves
to ResponseFormatUndefined when no responseFormat is provided.
Also adds integration tests covering toolStrategy, providerStrategy,
combined tools + responseFormat, nested schemas, and subagents with
structured output.

* fix(skills): update integration tests to use systemMessage API
The integration tests were using the old systemPrompt string API
but wrapModelCall now uses request.systemMessage.concat(). Updated
tests to pass SystemMessage objects and read from systemMessage.text.
