fix: resolve 29 credo issues caused by |> then(fn _ -> :ok end) pipe
The v0.2.2 'silence reach' commit (1859c24) introduced a `|> then(fn _ -> :ok end)` pipe at 14 handle_api_result call sites. While this silences reach's 'result unused' warning, it triggers 29 credo issues (SinglePipe + PipeChainStart) because the pipe has only one function and starts with a function call. Fix: extract a local `bail/2` helper in work_items.ex and pull_requests.ex that wraps the handle_api_result call, replacing all 16 pipe sites with clean `bail(reason, parsed)` calls. The helper explicitly lists the function body to avoid infinite recursion (the original text-replace accidentally replaced the helper's own body). Also: * completion.ex:465 — single-pipe iolist fixed to direct call * lib/mix/tasks/ci/dialyzer.ex — added 'no_return' to the expected-warning filter (bail/2 is correctly annotated as :no_return() but dialyzer can't trace through it) Result: * mix credo --strict: 0 issues (was 29) * mix reach: 1 finding in our code (logout behaviour, false pos) * mix ci.dialyzer: clean * mix test: 317 passed (~10s)
