alonso.torres 3953129adb 🐛 Resolve direction edits for empty generated grids
Allow direction edits on eligible grid containers without requiring cells.
Keep cell edits limited to grids with an existing cell. Add an opt-in empty
grid fixture without changing random operation distributions.

Cover main and copy scopes, nested grids, meaningful edits, skipped cell
edits and exact undo/redo. Add reset, update-main, duplicate, detach, child
addition and direction-return histories in common and frontend runners.
The original 40 assertions failed 16 times before the fix and pass unchanged.

Validation: full common JVM/JavaScript and frontend suites; backend/exporter
CI; common/frontend lint and format. All six common component properties
pass 40 programs at seed 712 in both runtimes. Focused common: 61 assertions;
frontend controls: 56 direction and 204 history assertions.
No production code changed; no sync benchmark was required.
