docs: document annotation row cache chokepoint and archive plan

update ARCHITECTURE.md and CLAUDE.md with the annotation visual-row
chokepoint invariant: renderWrappedAnnotation and
wrappedAnnotationLineCount must agree, both routed through
annotationVisualRows with a per-signature cache invalidated on file
load and theme apply.

archive the implementation plan under docs/plans/completed/.
