deps: add send2trash

Deletes are about to become recoverable, and send2trash is what every desktop
already understands: the freedesktop trash specification on Linux (its own
implementation unless PyGObject/GIO is there), the Finder trash on macOS and the
Recycle Bin on Windows. It is pure Python over ctypes — no compilation, no
runtime dependencies — so it can sit on the default install instead of behind an
extra.

A required dependency rather than an optional one on purpose: a missing extra
would silently turn "recoverable" into "gone", and a safety net that disappears
without a word is worse than no safety net.
