Unreleased

Initial release.

Mutare.Oban.WorkerReturn (:oban_worker_return) — swaps perform/1 return values for other valid Oban returns (:ok/{:ok, v} → {:error, :mutare}; {:error, reason} → :ok / {:cancel, reason}; {:cancel, reason} → {:error, reason} / :ok; {:snooze, s} → :ok; legacy {:discard, reason} → :ok / {:cancel, reason} and bare :discard → :ok). Behaviour-gated: fires only inside Oban.Worker / Oban.Pro.Worker modules, and reaches branch tails via return_replacements. Declares required_modules/0, so a run where Oban is not loadable aborts loudly instead of silently producing no mutants.
Mutare.Oban.Enqueue (:oban_enqueue) — rewrites MyWorker.new(args, opts) enqueue options (direct, aliased, or piped): max_attempts: n → 1 (n ≠ 1), and drops unique:, schedule_in:, and scheduled_at:.
Report notes on every mutant naming what a survivor leaves unasserted.
Ignore-variant labels on both families, so # mutare:ignore[oban_worker_return:ok] / # mutare:ignore[oban_enqueue:unique] can suppress one kind of mutant.
Mutare.Oban.all/0 for splicing both families into a :mutators list.
