📄 Description

Summary

Fixes textarea input variables losing line breaks after message submission on Windows.

Problem

When users paste or type multi-line text into a textarea prompt variable on Windows:

Text appears correct in the modal
After clicking "Save" and sending the message, all newlines are stripped
Editing the message reveals formatting is lost

Root cause: two issues working together:

Windows uses CRLF (\r\n) line endings which were not normalized
ProseMirror's schema.text() creates plain text nodes that discard newline characters — they need to be represented as hardBreak nodes

Solution

InputVariablesModal.svelte: Normalize Windows CRLF (\r\n) to LF (\n) before passing variable values to the editor.

RichTextInput.svelte: In replaceVariables(), split replacement text on newlines and create proper ProseMirror hardBreak nodes between text
segments instead of inserting raw newline characters.

Closes #21447

Changelog Entry

Description

Fix textarea prompt variables losing newlines on Windows in replaceVariables() and InputVariablesModal

Fixed

Textarea prompt variable newlines now preserved on Windows by normalizing CRLF line endings and converting newlines to ProseMirror hardBreak nodes
