fix(core): raise a clear error when langsmith cannot resolve the agent A tracer that sends runs to an agent passes its address to langsmith's get_run_url. A langsmith that has the agent class but not that argument now gets a ValueError saying so, instead of a TypeError. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

fix(core): build the run URL of a tracer that sends runs to an agent LangChainTracer.get_run_url did not tell langsmith which agent the run was sent to, so the URL was built for the default project, or failed. The tracer now passes its agent, and langsmith resolves it to the project. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

docs(langchain): describe both HITL interrupt modes with examples The class docstring said only "Human in the loop middleware." It now says what the middleware does, how the two modes pause and are answered, and shows a batched and a per-call example. The `interrupt_mode` argument is split into bullets with warnings for answering several calls at once and for middleware order.

docs(langchain): mark HITL `args_schema` fields as unused `InterruptOnConfig.args_schema` and `ReviewConfig.args_schema` were added with a TODO to fill them from the tool and never wired up, so neither mode sends them. Say so, point to `per_call` mode's `response_schema`, and drop the stale TODO.

fix(langchain): reject args an edit adds that the tool doesn't declare Edits accepted extra args when the tool's `args_schema` allowed them, so a reviewer could set fields the model is never told about. They're now held to the schema the model sees, whatever the tool's own `extra` setting.
