Closes https://github.com/zed-industries/zed/issues/38453 Current `Buffer` API only allows getting buffer text with `\n` line breaks — even if the `\r\n` was used in the original file's text. This it not correct in certain cases like LSP formatting, where language servers need to have original document context for e.g. formatting purposes. Added new `Buffer` API, replaced all buffer LSP registration places with the new one and added more tests. Release Notes: - Fixed ESLint linebreak-style errors by preserving line endings in LSP communication --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Kirill Bulatov <kirill@zed.dev>
