-Fix two O(n^2) editing slowdowns.
-
-1. Editing with UTF-16 / UTF-8 (byte) positions (the default in the JS binding)
-   validated each position by materializing the entire `[0, pos)` prefix string,
-   making every `insert`/`delete`/`splice`/`mark` O(n) and a run of edits O(n^2)
-   (regression since 1.12.0). The boundary check now reads the rope's prefix
-   caches via the cursor (O(log n)). Unicode-indexed editing was unaffected.
-
-2. When a subscriber is attached and many edits land on the same container within
-   one event batch (e.g. random-position inserts, or many distinct map-key
-   writes), building the event cloned the growing accumulated diff on every
-   compose — O(n^2) in the number of fragments. The diffs are now composed in
-   place. This affected text, map and list events.
-
-3. Converting a UTF-16 / UTF-8 position within a text chunk to a unicode offset
-   scanned the chunk char-by-char, so editing/slicing a large contiguous chunk
-   (a big insert, a loaded document, or a long run of typed text that merges into
-   one chunk) was O(chunk length) per op. Chunks that contain no astral-plane
-   characters (UTF-16) or are pure ASCII (UTF-8) now convert in O(1), covering
-   essentially all real-world text (ASCII/Latin/CJK).
