* fix(executor): strip orphan reasoning ids when store is disabled
Codex backend requires store=false and treats reasoning items with an
id but no usable encrypted_content as store lookups, which 404 with
"Item with id not found". Drop those orphan ids after removing invalid
encrypted_content (and when encrypted_content is already missing),
while preserving ids when store=true.
* fix(executor): skip id delete when reasoning item has no id
Avoid sjson.Delete on encrypted_content drops that never carried an id,
matching the orphan-id path's Exists() guard.
Previously each dropped encrypted_content re-ran sjson.DeleteBytes on
the whole body/array per item, causing O(n^2) work on inputs with many
reasoning items.
Now the array is walked once, editing only offending items in place
and lazily building a replacement "input" array via strings.Builder.
The builder stays nil (no allocation) when nothing needs sanitizing,
and the array is spliced back with a single SetRawBytes call.
