[project-history] fix convertToDiffUpdates when track delete is moved by previous op (#17681)
* [project-history] fix convertToDiffUpdates * fix test * preserve source ranges for applyRetain * use sourceRanges for applyDelete * use cursor difference for offset * move statement to closer to original * handle deletion before tracked delete * Revert "handle deletion before tracked delete" This reverts commit 6f2570f22473bd64516c166b29a34639ec701230. * using resultCursor and sourceCursor * refactor, use scanCursor * skip track delete properly * prettier * remove .sort() in applyRetain * small test fixes GitOrigin-RevId: 94755c219c90d6fedcdc64284d71137cf56d2442
