docs: move per-task cache check under task branch in decision tree

Per-task cache: false only applies to tasks (scripts can't have it),
so it belongs under the task branch, not before the task/script split.

 In short: **tasks are cached by default, scripts are not.** `--no-cache` turns off caching for everything. `--cache` is equivalent to `cache: true` — it enables both `cache.tasks` and `cache.scripts`, but cannot override a task's per-task `cache: false`.
