```
(show-option client name &key scope target (key nil key-p) (include-inherited t) cancel-token timeout output-limit (record-limit 4096) (value-limit 1048576))
```

Acquire one decoded option; return VALUE, PRESENT-P and a read-outcome vector.
False returns NIL,T; absence returns NIL,NIL. KEY selects an entry only after
acquiring a whole named array. A missing key does not fall through a present
local array. Mutable key text is copied before I/O and bounded to 1 MiB UTF-8.
Keys normalize under the exact live catalog before payload reads.
Scopes, limits, inheritance, ownership and failure evidence follow SHOW-OPTIONS.
