gmc wt dup creates multiple temporary candidate worktrees.

gmc wt dup 3 --task todo.md--task can be repeated to copy more context files into each candidate.
JSON output
gmc wt dup 3 -o jsonPrints one result per candidate with the same fields as gmc wt add -o json.
Creation stops at the first failing candidate; the array lists the candidates
already created plus the failed one, and the command exits non-zero.
