fix: enforce strict ruff lint (17 rule sets) across entire repo

- Expand ruff config from E/F to 17 rule sets (B, RUF, SIM, PIE, T20,
  ARG, ERA, A, BLE, RET, ISC, TCH, UP, C4, PERF)
- Fix 907 lint errors across all Python files (GUI, FPGA cosim,
  schematics scripts, simulations, utilities, tools)
- Replace all blind except-Exception with specific exception types
- Remove commented-out dead code (ERA001) from cosim/simulation files
- Modernize typing: deprecated typing.List/Dict/Tuple to builtins
- Fix unused args/loop vars, ambiguous unicode, perf anti-patterns
- Delete legacy GUI files V1-V4
- Add V7 test suite, requirements files
- All CI jobs pass: ruff (0 errors), py_compile, pytest (92/92),
  MCU tests (20/20), FPGA regression (25/25)
