Exposes pm3py as a pyws workspace, discovered via the pyws.plugins entry point:
- ReaderResource: connects/disconnects a Proxmark3 as `reader`; a missing device is
non-fatal (reports disconnected)
- namespace injection of the transponder/sim classes, SimSession and Proxmark3
- effect declarations so autoreplay/replay withhold writes/field/sim/destructive while
reads and pure model edits replay
Hardware-free tests via AsyncMock. The live `sim` resource is P2.
