kshitijk4poor 4d0cec9a7d fix(agent): the pre-API-call /steer drain also stops smearing the persisted tool row
Second site of the same bug class #104444 fixes in apply_pending_steer_to_tool_results:
_inject_steer_into_newest_tool_result (the drain that runs when a /steer lands during an
API call) mutated the newest role:tool row in place. That row was already flushed
append-only, so the replayed history diverged from the live request bytes at the
injection point and broke the prompt cache exactly like the post-batch path.

Deliver it the same way: a standalone user row inserted right after the newest tool
result (not yet persisted, so the next flush writes it to the transcript). Restash when
there is no tool row yet, unchanged. Stale comments claiming steer lands "in the newest
tool result" and agent/AGENTS.md's alternation rule now describe the real shape.
