## Context

We're seeing issues where large edits (think generated, agentically or
otherwise) or edits in files with very large lines cause ep requests to
fail until they are flushed from the history due to the request body
exceeding the endpoint size limit. These edits are large enough they
would be omitted from the final prompt anyway due to budgeting so it is
safe to drop them client side.

## How to Review

<!-- Help reviewers focus their attention:
- For small PRs: note what to focus on (e.g., "error handling in
foo.rs")
- For large PRs (>400 LOC): provide a guided tour — numbered list of
files/commits to read in order. (The `large-pr` label is applied
automatically.)
     - See the review process guidelines for comment conventions -->

## Self-Review Checklist

<!-- Check before requesting review: -->
- [x] I've reviewed my own diff for quality, security, and reliability
- [x] Unsafe blocks (if any) have justifying comments
- [x] The content is consistent with the [UI/UX
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)
- [x] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

Release Notes:

- Fixed an issue where large changes to buffers, or edits in buffers
with extremely long lines would cause edit prediction requests to fail
