d5b7e98750 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

b339f302d3 Add TRT-LES diagnostics and plotting functionality 
- Introduced new functions for computing and plotting TRT-LES fields.
- Enhanced case diagnostics to include mass drift and inlet variance metrics.
- Updated configuration to support inlet profile selection and TRT magic parameter.
- Modified existing functions to accommodate new diagnostic calculations.
- Improved case tagging to include inlet profile and TRT parameters.
- Added checks for fluid dynamics and diagnostics in the run_case function.
