application(_:open:) forwards every Finder-delivered URL to
AppModel.openBoard(at:) — the exact path welcome and File > Open use, so
a Finder open gets the same registry record-before-load, recents stamp,
already-open-focuses-its-window dedup, and row-level failure surfacing
on welcome (DESIGN/02 > Launch). A cold Finder launch can arrive before
any scene has captured the window opener; openBoard now buffers such
URLs and captureWindowActions replays them once opening is possible.

Four scenes (welcome, restore bootstrap, board group, card group) with
system restoration disabled in favor of the registry's open-now flags:
set when a window actually opens, cleared only on user close, so quit —
and crash — leave exactly the restoration set behind. AppModel joins
windows to sessions (shared store, registry record, card refs, held
security scope); CloseFlushCoordinator pins 02's strict close order as
a seam-injected machine (card sessions end, windows drain, store
flushes, record stamps, teardown) with named slots where m6/m7 flushes
land. HostedWindowController proxies — never replaces — SwiftUI's
window delegate to intercept windowShouldClose for the flush, report
frames, and place saved frames onto live screens. Card windows are
(board path, case-folded card id) values: reopen focuses, and a
snapshot-pure fate function dismisses on delete, tombstone, tombstoned
lane, or cross-board move.
