CX#5 (newline-boundary streaming gate):
- New crates/tui/src/tui/streaming/line_buffer.rs — LineBuffer holds
text after the last \n until the next \n arrives, so partial code
fences never become visible state.
- Wired into BlockState in streaming/mod.rs. Assistant text gates;
thinking deltas bypass (reasoning stays live).
- 9 unit tests including the partial-fence regression case.
CX#11 (pure-render footer):
- New crates/tui/src/tui/widgets/footer.rs — FooterProps / FooterToast
/ FooterWidget. Pure render of pre-computed props.
- ui.rs::render_footer rewritten to build props once and delegate to
FooterWidget. Visual output identical; existing 10 footer tests
pass unchanged. 5 new from_app tests for the props builder.
908/908 tests pass; cargo clippy --workspace -D warnings clean;
cargo fmt clean.
