- Lazily compute document line hashes, avoid redundant multiline insertion
walks, and defer longest-line measurement for large or exceptionally long
text changes.
- Cache default code editor keybindings, reserve common command storage, and
create UIDiffView image viewers only when an image diff requires them.
- Keep cached screen positions coherent when descendants are queried before
dirty ancestors, and add regression coverage for ancestor movement.
- Relocate font-rendering golden images into the unit-test asset directory
and resolve image fixtures independently of the current working directory.
- Fix spurious status entries for files moved between directories. Preserve the suffix after Git's abbreviated brace notation when parsing renamed paths from numstat output. This prevents directory moves such as `bin/{ => unit_tests}/assets/...` from producing truncated synthetic untracked entries like `unit_tests`. Add regression coverage for staged files moved into a different directory.
- Git Plugin now remembers between sessions the uncommited commit message.
