feat(code): add hide whitespace changes toggle to diff viewer#1385
Conversation
Adds a "Hide whitespace changes" option to the diff viewer dropdown menu. When enabled, whitespace-only differences are filtered out of the diff using a custom override of the @codemirror/merge diff algorithm, similar to git diff -w.

@k11kirky Yep, collapse/expand unchanged lines and hiding/showing whitespace diffs are the most perfectly and accidentally complementary features ever. Conflict fixed! |

Problem
When reviewing diffs with formatting or indentation changes, the meaningful code changes get obscured by whitespace noise. There's no way to filter these out in the diff viewer.
Changes
Adds a "Hide whitespace changes" toggle to the diff viewer's
