Jason	51740fd6f5	test(fpga): F-3.2 add DDC cosim fuzz runner with seed sweep A new SCENARIO_FUZZ branch in tb_ddc_cosim.v accepts +hex / +csv / +tag plusargs so an external runner can pick stimulus and output paths per iteration. The three path registers are widened to 4 kbit each so long temp-directory paths (e.g. /private/var/folders/...) do not overflow the MSB and emerge truncated — a real failure mode caught while writing this runner. test_ddc_cosim_fuzz.py is a pytest-driven fuzz harness: - Generates a random plausible radar scene per seed (1-4 targets with random range/velocity/RCS/phase, random noise level 0.5-6.0 LSB stddev) via radar_scene.generate_adc_samples, fully deterministic. - Compiles tb_ddc_cosim.v once per session (module-scope fixture), then runs vvp per seed. - Asserts sample-count bounds consistent with 4x CIC decimation, signed-18 range on every baseband I/Q word, and non-zero output (catches silent pipeline stalls). - Ships with two tiers: test_ddc_fuzz_fast (8 seeds, default CI) and test_ddc_fuzz_full (100 seeds, opt-in via -m slow) matching the audit ask.

test(fpga): F-3.2 add DDC cosim fuzz runner with seed sweep

A new SCENARIO_FUZZ branch in tb_ddc_cosim.v accepts +hex / +csv / +tag
plusargs so an external runner can pick stimulus and output paths per
iteration. The three path registers are widened to 4 kbit each so long
temp-directory paths (e.g. /private/var/folders/...) do not overflow
the MSB and emerge truncated — a real failure mode caught while writing
this runner.

test_ddc_cosim_fuzz.py is a pytest-driven fuzz harness:
 - Generates a random plausible radar scene per seed (1-4 targets with
   random range/velocity/RCS/phase, random noise level 0.5-6.0 LSB
   stddev) via radar_scene.generate_adc_samples, fully deterministic.
 - Compiles tb_ddc_cosim.v once per session (module-scope fixture),
   then runs vvp per seed.
 - Asserts sample-count bounds consistent with 4x CIC decimation,
   signed-18 range on every baseband I/Q word, and non-zero output
   (catches silent pipeline stalls).
 - Ships with two tiers: test_ddc_fuzz_fast (8 seeds, default CI) and
   test_ddc_fuzz_full (100 seeds, opt-in via -m slow) matching the
   audit ask.

Registers the "slow" marker in pyproject.toml for the 100-seed opt-in.

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)

fix: full-repo ruff lint cleanup and CI migration to uv

Resolve all 374 ruff errors across 36 Python files (E501, E702, E722,
E741, F821, F841, invalid-syntax) bringing `ruff check .` to zero
errors repo-wide with line-length=100.

Rewrite CI workflow to use uv for dependency management, whole-repo
`ruff check .`, py_compile syntax gate, and merged python-tests job.
Add pyproject.toml with ruff config and uv dependency groups.

CI structure proposed by hcm444.
