List Workflows

List workflows in the current workspace. Returns a counted, paginated list of workflows scoped to the `X-Workspace-Id` header. Each item includes aggregate stats (`runs_count`, `last_run_at`, `last_run_status`) computed over all runs for that workflow. **Status filter:** `status` narrows by the UI-derived state of the workflow's most recent run. `completed` matches only workflows whose latest run succeeded (completed-only), and `failed` matches only workflows whose latest run failed — the two buckets are disjoint. A workflow whose latest run was `cancelled` matches neither bucket and surfaces only in the unfiltered list. `running` matches active (running or paused) workflows. `draft` matches workflows with no runs yet. `paused` is accepted but currently returns no results. **Multi-sort:** `sort` and `order` are parallel query lists. `?sort=runs_count&sort=name&order=desc&order=asc` orders primarily by `runs_count DESC`, then by `name ASC`. When `order` has fewer entries than `sort`, missing positions use per-field defaults (`name=asc`, `updated_at=desc`, `runs_count=desc`). Omitting `sort` defaults to `updated_at DESC`. A stable `id ASC` tiebreaker is always appended so offset/limit pagination is consistent when sort keys tie. **Date range:** `last_run_after` / `last_run_before` filter by the time of the most recent run. Both must be ISO 8601 with a UTC offset; a naive datetime returns 422. An inverted range (`after > before`) also returns 422. **Failure history:** `has_failed_run` is orthogonal to `status`. `status` keys off the latest run only; `has_failed_run=true` matches workflows with a `failed` run *anywhere* in their history, so a workflow whose latest run completed still matches if an earlier run failed. It composes with the other filters (AND). `cancelled` runs do not count as failures. `pagination.total` reflects the filtered count for the current query.
