/**
 * Backward-compatible single-object form accepted by defineTask.
 * Two flavors are recognized:
 *   1. Static TaskDef shape: { id|name, kind, title, labels, ...rest } — the
 *      whole object (minus id/name/run/source/inputs/outputs) is treated as a
 *      static TaskDef returned for every invocation.
 *   2. Run-function shape: { id|name, run(args, ctx) -> TaskDef|Promise<TaskDef>,
 *      description?, labels?, kind?, source?, inputs?, outputs? } — `run` is
 *      used as the impl. `inputs`/`outputs` schemas are stored as metadata for
 *      tooling but are not enforced at runtime.
 *
 * This shape is used by ~75 library/contrib and library/methodologies files
 * authored against an earlier SDK API; supporting it here keeps those processes
 * runnable without per-file rewrites.
