- Replace split zero_force_segment / zero_sensor_segment with unified
zero_obs_async() — a single memset covers all three obs segments
(force, torque, sensor), resetting the step accumulator.
- Add _obs_accum_steps counter so read_*(normalize=True) returns the
physically meaningful per-step average for all telemetry fields.
- Sensor now always applies area-normalisation internally; the normalize
parameter only controls the additional time-normalisation step.
- run() gains zero_obs=True parameter (default) to control reset-on-step.
- 7 new integration tests covering accumulation, zeroing, and normalise.
- Fix bug in test_sensor_accuracy.py (undefined loop variable i).
- Bump version to 0.4.0 for the API change.

- Add runtime body topology sync (add_body/remove_body + sync_bodies)
with recompile, DDF patch (feq + BFS inward fill), and commit.
- Unify action/obs flow: set_body/set_force are now host-only;
run() auto-uploads action and downloads obs via CUDA stream.
- Add read_body(id) -> BodyTelemetry and read_bodies() for DRL loops.
- Add FRC_REGION flag (0x0800) for force_region cells.
- Extract equilibrium helpers (lbm/equilibrium.py) and DDF patch module
(body/ddf_patch.py).
- Merge recompile / _runtime_recompile into single _recompile().
- Add n_objects to checkpoint; validate on load.
- Add test suite: 40 unit + 19 integration tests (59 total).
- Add conftest.py and docs/tests_overview.md for test documentation.
- Update README.md and CONFIG.md for new API.
