+/**
+ * Apply a visitor to a CST document or item.
+ *
+ * Walks through the tree (depth-first) starting from the root, calling a
+ * `visitor` function with two arguments when entering each item:
+ *   - `item`: The current item, which included the following members:
+ *     - `start: SourceToken[]` – Source tokens before the key or value,
+ *       possibly including its anchor or tag.
+ *     - `key?: Token | null` – Set for pair values. May then be `null`, if
+ *       the key before the `:` separator is empty.
+ *     - `sep?: SourceToken[]` – Source tokens between the key and the value,
+ *       which should include the `:` map value indicator if `value` is set.
+ *     - `value?: Token` – The value of a sequence item, or of a map pair.
+ *   - `path`: The steps from the root to the current node, as an array of
+ *     `['key' | 'value', number]` tuples.
+ *
+ * The return value of the visitor may be used to control the traversal:
+ *   - `undefined` (default): Do nothing and continue
+ *   - `visit.SKIP`: Do not visit the children of this token, continue with
+ *      next sibling
+ *   - `visit.BREAK`: Terminate traversal completely
+ *   - `visit.REMOVE`: Remove the current item, then continue with the next one
+ *   - `number`: Set the index of the next step. This is useful especially if
+ *     the index of the current token has changed.
+ *   - `function`: Define the next visitor for this item. After the original
+ *     visitor is called on item entry, next visitors are called after handling
+ *     a non-empty `key` and when exiting the item.
