feat(obs): unified zero_obs control and time-normalised readback

- 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.

feat(compat): FP16S and ddf_shifting compatibility, EsoPull curved closure

Phase A: FP16S store precision verification
- Kan99b K2 FP16S: quantization sensitivity documented (St 0.170 -> 0.142)
- Sah04 S2 FP16S: PASS (St error 1.53% within 5% gate)
- Sah04 S4 FP16S: diverges at high blockage (known limitation)

Phase B: ddf_shifting code fixes
- Fix inlet west_velocity_rho_closure for shifted DDF (common.cuh)
- Fix curved force/torque accumulation for shifted DDF (curved_boundary.cuh, aux_kernels.cu)
- Fix host upload_ddf() asymmetry (field.py)
- Add checkpoint streaming/ddf_shifting match check (checkpoint.py)
- MRT shifting fix: MRT is NOT shift-invariant; unshift/reshift around collision
- Generalize inlet knowns repair from Zou-He to all west inlet schemes

Phase C: EsoPull curved boundary semantic closure (from round 2)
- streaming/esopull_semantic_helpers.cuh: single truth for physical-value semantics
- step/esopull_macro.cu: MacroscopicEsoPullKernel for correct GPU diagnostics
- SensorKernel, ForceRegionKernel share semantic helpers
- Kan99b K2: bit-identical to double-buffer
- Code-level comments document compatibility boundaries
- README updated with compatibility matrix
- output/round3_compatibility_summary.md: full round documentation
