feat(editor): add --clone-item for items.json parity with clone-creature/object/quest

Browse source 
Duplicates the entry at given 0-based index. Auto-assigns the
smallest unused positive id so numbering stays contiguous. Optional
<newName> argument overrides the cloned name; without it the new
entry appends " (copy)" to the original name (matches the
established convention from --clone-creature).

Useful for variant items: clone "Iron Sword" → "Steel Sword" and
edit just the displayId, instead of typing every field again.

Verified: clone with no name override → "Iron Sword (copy)" id=2;
clone with explicit "Steel Sword" → id=3 (next free); fields
(quality, ilvl, displayId) preserved verbatim; out-of-range index
99 fails with exit 1. Brings command count to 199.
