Mirror the Query.fetch() cleanup from TanStack#11163 so a settled Mutation no longer retains its Retryer (and closed-over variables/result) for the MutationCache lifetime. Fixes TanStack#11216

ChangesMutation retryer release
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The mutation cleanup change is localized, but the re-entrant execution path that protects a newer retryer from being cleared is not directly covered. This is a bounded correctness risk for owner follow-up and does not block merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Add a re-entrant execution test for the identity guard.
The current test calls mutation.continue() at Line 1187 after the first execute() has already resolved. This does not verify the case where a second execution replaces this.#retryer before the first finally block runs. Add a test that starts a second execution from an onSettled callback and confirms that the first cleanup does not clear the newer retryer.

Summary
Fixes #11216.
Mutation.execute()keptthis.#retryerafter the mutation settled, whileQuery.fetch()already clears it after #11163. The settled retryer promise retains that mutation's variables and result for as long asMutationCachekeeps the instance.This change mirrors the query cleanup: capture the local retryer, clear
this.#retryerinfinallywhen it still owns that instance, then run the next queued mutation.Validation
