chore(cli): re-pin go-flashduty to merged main (follow-up to #52)

#52 merged at the pre-re-pin commit, so feat/ai-sre pinned the go-flashduty#11
PR-branch commit (da82c4) rather than the squash-merged main commit. Re-pin to
go-flashduty main (54d4fc1) so the dependency tracks main, not an orphaned
PR-branch commit kept alive only by the closed PR. Generated output unchanged
(identical spec); build + unit tests pass.
