## Message

```
vim: Fix paste crash with out-of-order marks (#64876)

## Summary

Pasting multiple selections at the end of a file could crash Vim while
saving paste marks, because their anchors are not necessarily in
document order. Serialize those marks with a summarizer that reuses its
cursors while moving forward and resets them when an anchor moves
backward, preserving mark order.

Fixes
[FR-506](https://linear.app/zed-industries/issue/FR-506/zed-c22-cannot-summarize-backward-from-26-to-23).

## Testing

In Vim mode, copy `abcdef` and `xyz` as two separate selections in Zed.
Open a saved file containing `012345678901234567890` with no trailing
newline, put one cursor on the final `0`, and press `p`. The paste
should complete without crashing.

## Self-review

performance.

Vim mode.
