/**
* Cursor is a stable position representation in the doc.
* When expressing the position of a cursor, using "index" can be unstable
* because the cursor's position may change due to other deletions and insertions,
* requiring updates with each edit. To stably represent a position or range within
* a list structure, we can utilize the ID of each item/character on List CRDT or
* Text CRDT for expression.
*
* Loro optimizes State metadata by not storing the IDs of deleted elements. This
* approach complicates tracking cursors since they rely on these IDs. The solution
* recalculates position by replaying relevant history to update cursors
* accurately. To minimize the performance impact of history replay, the system
* updates cursor info to reference only the IDs of currently present elements,
* thereby reducing the need for replay.
*
* @example
* ```ts
*
* const doc = new LoroDoc();
* const text = doc.getText("text");
* text.insert(0, "123");
* const pos0 = text.getCursor(0, 0);
* {
*   const ans = doc.getCursorPos(pos0!);
*   expect(ans.offset).toBe(0);
* }
* text.insert(0, "1");
* {
*   const ans = doc.getCursorPos(pos0!);
*   expect(ans.offset).toBe(1);
* }
* ```
