Classify & Copy polish — in either target tab the goal is to assign or exclude
every left-pane file until nothing remains:
- Hide Assigned checkbox (classify mode, in the folder-tree pane header):
collapses the source tree to only what's left on the ACTIVE axis — hides
files already assigned in the current tab (or excluded) and any folder whose
scanned subtree is thereby empty. Re-renders on tab switch; target-tree
exposes activeAxis().
- Node add/edit/delete controls moved to the LEFT of the level name and made
always-visible (was right-aligned + hover-only), so building/pruning the
tracking and transmittal trees is one click.
- Brace expansion in the add-folder box: "BMB-187023-{PM,EL,EM}-MOM-
{0001-0002,0005}_A (IFR)" creates all 9 folders — {a,b} alternation +
{N-M} zero-padded numeric ranges, cartesian product across groups; a
multi-create is confirmed first. New classify.expandFolderPattern().
Tests: expandFolderPattern unit cases + a Hide-Assigned DOM test
(classify.spec.js → 29 passed; classifier.spec.js → 4 passed).
