Building on top of #150, this PR adds automatic instrumentation for langchain. Now when you call braintrust.auto_instrument() you'll get langchain automatically instrumented.

Add a CallbackPatcher base primitive and use it to model LangChain as an SDK integration that installs a default Braintrust callback handler. Export the LangChain integration, wire it into auto_instrument(), and add focused setup and auto-instrument tests.

Also document CallbackPatcher usage in the sdk-integrations skill so future integrations can use the same pattern for setup-only side effects.

feat(langchain): add callback patcher integration
cbf491d
Add a CallbackPatcher base primitive and use it to model LangChain as an SDK integration that installs a default Braintrust callback handler. Export the LangChain integration, wire it into auto_instrument(), and add focused setup and auto-instrument tests.
Also document CallbackPatcher usage in the sdk-integrations skill so future integrations can use the same pattern for setup-only side effects.

Building on top of #150, this PR adds automatic instrumentation for langchain. Now when you call braintrust.auto_instrument() you'll get langchain automatically instrumented.
Add a CallbackPatcher base primitive and use it to model LangChain as an SDK integration that installs a default Braintrust callback handler. Export the LangChain integration, wire it into auto_instrument(), and add focused setup and auto-instrument tests.
Also document CallbackPatcher usage in the sdk-integrations skill so future integrations can use the same pattern for setup-only side effects.
