Remove fragment from sidebar controls (not supported)
...
Sidebar controls cannot be in a fragment. Brief blank on
slider change is a Streamlit limitation.

Restructure package for domain-driven design
...
Reorganise package structure to improve separation of concerns:
- instruments/ - SCPI, transport, drivers, interfaces, factory
- simulation/ - physics engine, virtual instruments, server
- framework/ - test runner, logger, limits, context
- tests/ - thermal/, electrical/ (DVT test implementations)
- data/ - repository, models
- reporting/ - generator, templates
- app/ - CLI, config, dashboard
This structure enables:
- Reusable instruments package for other test suites
- Clear separation of simulation (dev) vs production code
- Domain-focused package organisation
Updated documentation to reflect new paths.
