Replace the flat file list with a hierarchical tree view so users can quickly identify the blast radius of a change by directory structure. Directories show aggregate line counts and file counts, with expand/collapse support via click, Enter, and arrow keys. Single-child directory chains are compacted (e.g. src/components/ui). https://claude.ai/code/session_0182VcA2o9BnKzEF1GNhjzkK
- Snap selection to collapsed directory when the selected item is a child being hidden, instead of leaving it on an unrelated row - Switch from <For> to <Index> for better render performance since flattenVisibleTree returns new objects each time - Avoid unnecessary array allocation in compaction loop https://claude.ai/code/session_0182VcA2o9BnKzEF1GNhjzkK
…s reduce - Reduce per-level indentation from 16px to 10px - Wrap toggleDir state updates in batch() to prevent intermediate flushes - Replace triple reduce with single loop for directory aggregate stats - Replace spread push with for-of loop in flattenVisibleTree
