Mark every hand-rolled shared/ui surface with a `// CIBG-GAP EXTENSION:`
comment + `cibgGap` story parameter (skeleton, spinner, rich-text-editor,
wizard-shell's error summary, application-link's non-navigating row,
debug-state, status-badge, card, placeholder-chip) so deviations from the
CIBG design system are auditable. Add the register MDX
(Foundations/CIBG Gap Register), cross-linked from ADR-0003. Delete the
near-identity upload-status-banner wrapper; its one consumer now uses
<app-alert> directly (a story added to keep the info-banner state covered).
