Closes https://github.com/zed-industries/zed/issues/41935 The registration ID responsible for generating each diagnostic is now tracked. This allows us to replace only the diagnostics from the same registration ID when a pull diagnostics report is applied. Additionally, various deficiencies in our support for pull diagnostics have been fixed: - Document pulls are issued for all open buffers, not just the edited one. A shorter debounce is used for the edited buffer. Workspace diagnostics are also now ignored for open buffers. - Tracking of `lastResultId` is improved. - Stored pull diagnostics are discarded when the corresponding buffer is closed. Release Notes: - Improved compatibility with language servers that use the "pull diagnostics" feature of Language Server Protocol. --------- Co-authored-by: Kirill Bulatov <mail4score@gmail.com> Co-authored-by: Kirill Bulatov <kirill@zed.dev>
