Materialize the trash — faces, menus, and grammar

Phase 3 finishes the pivot at the surface. One card face serves two
containers: CardFaceView extracted with a role — board or trash — so
stripe, tint, chip, selection stroke, cut dim, marquee registration,
and drag are shared by construction, the trash side differing only in
its absences: no Open, no rename, no Style, no file-hover highlight,
and a Delete that goes through the confirmation host. The column
rewrote around the lanes' own single-column masonry so drag reflow
reads as positional slides; chrome stays the hatched header, symbol,
and count — 11 gives Empty Trash to the File menu alone. Two real
grammar bugs die here: plain Backspace on a trash selection purged
without the confirmation the menu raises, and the context menu's
Delete resolved against the standing selection, so right-clicking a
trash card under a board selection silently did nothing — it now
stages the clicked set explicitly. Open, Rename, Style, and Empty
Trash validation became testable store seams; the column is one named
accessibility container of ordinary card elements. The tombstone era
is swept: deleteItem, restoreItem, stripTombstonedChildren — dead
since lane copies stopped nesting trash — the restore verb, the
unreachable put-back banner row, and every quasi-lane doc comment.
