* 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
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.

* refactor(deepagents): migrate memory middleware to use SystemMessage
Update memory middleware to use SystemMessage class instead of string-based systemPrompt. This change aligns the middleware with the updated request interface and provides better type safety.
- Replace systemPrompt string with SystemMessage object in memory.ts
- Use SystemMessage.concat() method for combining memory section with existing system message
- Update all test cases to use SystemMessage constructor and .text property for assertions

* fix(deepagents): prevent infinite loop when read_file returns large content (#82)
When a tool returned a large result with few but very long lines, the
agent could enter an infinite eviction/read loop. The content would be
evicted to the filesystem, then read_file would return all the content
(since it only had a line limit, not a character limit), which would
again exceed the eviction threshold.

* fix(middleware): avoid unnecessary REMOVE_ALL_MESSAGES in PatchToolCallsMiddleware
The middleware was unconditionally triggering REMOVE_ALL_MESSAGES on every
request, even when there were no dangling tool calls to patch. This caused
unnecessary frontend re-renders and UI flickering when using useStream with
fetchStateHistory: true.
Added a needsPatch flag to track whether any dangling tool calls are found,
and only trigger the state rebuild when patching is actually needed.
