* fix(skills): keep a slash skill activation when the model call is retried SkillActivationMiddleware records the activated slash message in the run context before it calls the model. LLMErrorHandlingMiddleware sits outside it and retries a failed (429/503/timeout) or empty call by running this wrap again on the same request; the retry found the run key already set and went out without the SKILL.md body, while the slash source it had published kept the skill's tool restrictions in force. Record the activation itself next to the run key and replay it while nothing has answered the slash message yet: a retry sees no AI message after the target, a tool-loop follow-up call does. The replay carries the same reminder and usage stamp without re-reading the skill or repeating the audit event and usage record, which now sit with the other once-per-activation side effects. Two existing tests sent the same unanswered request twice to model a follow-up call; that is the retry shape, so their second call now includes the first response, as the real graph does. * docs(changelog): reference #6506 --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>
