CGH0S7 bd4ce3fbf3 GPU-accelerate Shell-Patch BSSN evolution 
Phase 1: Enable GPU resident state for Cartesian patches in Shell mode.
- Remove WithShell guard from bssn_cuda_use_resident_sync().
- Add GPU-to-CPU state sync before shell CPU consumers (SHStep,
  CS_Inter, inline shell RHS blocks).

Phase 2: GPU-accelerate BSSN Shell Patch RHS.
- Create bssn_gpu.h with RHS_SS_PARA macro and gpu_rhs_ss declaration.
- Fix compilation bugs in legacy bssn_gpu_rhs_ss.cu (deprecated
  cudaThreadSynchronize, tmp_con2 redeclaration, ijkmin3_h typo,
  CUDA_SAFE_CALL, missing compare_result guard).
- Add bssn_gpu_rhs_ss.o to CFILES_CUDA_BSSN with build rule.
- Write cuda_compute_rhs_bssn_ss() wrapper bridging Fortran and GPU
  parameter conventions, redirect all shell RHS call sites via #define.

Verified: 30-step Shell-Patch GPU run completes without errors/NaN.
Step wall time ~4.4s (step_fn ~2.0s + RP ~0.68s + constraint ~0.70s).

prolong3 改为先算实际 stencil 窗口；只有窗口触及对称边界时才走全域 symmetry_bd，否则只复制必需窗口。restrict3 同样改成窗口判定，无触边时仅填 ii/jj/kk 必需窗口。
