simulator:attribute catchup with real SCAN
What changed, and why it matters
This commit makes two small, unrelated tweaks to the Coldcard simulator. One adds copy-and-paste keyboard shortcuts to the simulator's terminal window. The other adds a missing 'busy_scanning' flag to the simulated QR-code scanner so it behaves more like the real hardware. Neither change affects real Coldcard devices or their security.
No security action needed. This is a routine simulator maintenance commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff updates unix/simulator.py to pass extra XTerm resource settings enabling CLIPBOARD-based selection and Ctrl+Shift+C/V bindings in the simulator’s REPL terminal. It also updates unix/variant/sim_scanner.py to initialize self.busy_scanning = False in the SimulatedQRScanner class, matching an attribute present in the real QRScanner implementation. Both changes are simulator-only and have no effect on firmware running on actual devices.
