- projection_layout builds ProjectedTableLayout geometry (fixed 160x28
cells matching the legacy bridge width, merge spans with covered-cell
flags) and per-block origins so blocks after a table clear it instead
of using the fixed line step
- ProjectionRenderer draws the table grid through a new draw_table_border
live field and consumes layout block origins for text placement
- table_hit_test maps points to merge-anchor cells for future cell editing
- doc-engine: split the cramped style-patch line clippy flagged as
possible_missing_else; the crate is clippy-clean again
- README: tick verified CRDT bridge boxes (dependency, wiring, selected
replacement/formatting/table/toolbar migration, font size/color
migration) and document the table milestone
- CI: add doc-engine workflow (engine tests + clippy -D warnings +
nigig-build consumer check/test) and trigger nigig-build CI on doc
changes
