Same hole and same shape as the merged pulls fix (#1111):
--output parses on issues create through the urfave/cli v3
ancestor-flag cascade but was never read, so the action always
printed glamour markdown plus a second bare URL line.
task.CreateIssue now returns the created issue and the cmd layer
switches on --output, emitting compact lean JSON (index, title,
url, state), matching the post-review shape of
writeCreatedPullAsJSON. Without the flag the output stays
byte-identical: the same print.IssueDetails and HTMLURL println
calls just moved to the callers.
