open-swe[bot] 17d1c274c4 fix(langchain): improve HITL rejection guidance (#37859) ...

Improves the default `reject` `ToolMessage` so models see that the human
denied the action, the tool was not executed, and the same call should
not be retried unless the user asks. Also documents that clients can
provide a custom `reject` message for domain-specific guidance.
