Draft split from #2649. Keeps the inline step completion persistence retry fix isolated from the broader streaming investigation.

Problem: when inline step_completed persistence fails with a transient infra/storage error, executeStep could catch that failure in the broad step execution path and record it as a user step retry/failure instead of letting the queue redeliver.

Fix: move step_completed persistence outside the user-code/dehydrate failure path, preserve EntityConflictError as skipped and RunExpiredError as gone, rethrow other completion persistence errors for queue retry, and add regression coverage proving no step_retrying or step_failed event is written for completion write failures.

Validation: Biome focused check, @workflow/core typecheck, step-handler Vitest file, simplify review loop, and autoreview local clean.

No backport to stable for b180270 (AI decision).

This fix targets packages/core/src/runtime/step-executor.ts and the executeStep function, neither of which exist on stable (step execution there lives in a differently-structured step-handler.ts monolith with no step-executor.ts). The bug being fixed is specific to the inline sequential execution path (sinceCursor/inlineDelta threading inside executeStep's try/catch), and the accompanying test changes rely on executeStep/baseParams/inline-delta test scaffolding that is entirely main-only, so the change builds on main-only behavior and does not apply to stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:
