Pure provenance core (recipe fingerprint, FX-chain identity, parent
detection) + shell reads; capture stamps provenance on resample-from-sample;
re-capture regenerates a provenanced sample from its source, never touching
the timeline. Adds BankIndex/BankBook in-place update. CTest-covered.
Pool grid on top, LICE-drawn named-banks tab strip below with overflow-scroll
(new pure tab_strip seam, unit-tested). Full-height toggles, unmistakable
active-bank readout distinct from the shown tab, tab context menu
(activate/rename/delete/evacuate/create) with rich confirm-on-non-empty-delete,
and move/copy via menu + drag with drop-highlighting. Fold-in: deserialize
auto-disambiguates duplicate folded bank names instead of rejecting the book.
