fix(newos4): define VirtualFS.emptyTrash() — empty-trash threw since 2026-10-18

Report RPT-20261018-164646-89352963 ("this.fs.emptyTrash is not a function") was filed by the auto-filer and never fixed: terminal.js:1777 called a method VirtualFS never defined, so 'empty-trash --confirm' threw instead of emptying. Added emptyTrash() returning true only when it removed something.

Verified live on v4.6.54: put -> rm -> empty-trash --confirm => 'Trash emptied.'; second run => 'Trash is already empty.'; .trash entries 0.
