GitLab Diff: Hide Renames, Shims & Noise

Hide rename, re-export-shim, import-only and comment-only files on GitLab merge request diff pages (classic diffs).

Big refactor merge requests bury the real changes under hundreds of low-signal files — pure renames, re-export "shim" stubs, import-path churn, and comment tweaks. This extension removes those from the GitLab MR file tree itself (not just greyed out), so the diff stays readable. Hide, with an independent toggle each: • Pure renames — moved files with no content change • Re-export shims — files whose body is only `export … from …` • Import-only changes — files whose only changed lines are `import … from …` • Comment-only changes — files whose only changed lines are comments Everything runs locally against your existing GitLab session. No data is collected, transmitted, or shared. Notes: • Works on classic GitLab diff pages. The beta "Rapid Diffs" view is not supported (the panel says so when it's active). • Currently scoped to gitlab.com.
