skip redundant MPI ghost cell syncs for stages 0, 1 & 2

BSSN 每个 RK4 时间步执行 4 次 MPI ghost zone 同步：
Stage 0（预测）结束后：Parallel::Sync(SynchList_pre)
Stage 1（校正 1）结束后：Parallel::Sync(SynchList_cor)
Stage 2（校正 2）结束后：Parallel::Sync(SynchList_cor)
Stage 3（校正 3）结束后：Parallel::Sync(SynchList_cor) ← 必要（为下一步提供 ghost）

-    Calculate 3D Vector RMS and component-wise RMS (X, Y, Z) independently.
+    Calculate trajectory-based RMS error on the XY plane between baseline and optimized simulations.
-    Uses r = sqrt(x^2 + y^2) as the denominator for all error normalizations.
+
-    Returns the maximum error between BH1 and BH2 for each category.
+    This function computes the RMS error independently for BH1 and BH2 trajectories,
+    then returns the maximum of the two as the final RMS error metric.

+## 6. Conclusions
+
+1. **Profile data is valid**: 1,392 functions instrumented, 117 exercised with ~4.2 billion total counts.
+2. **Hotspot concentration is high**: Top 5 functions alone account for ~76% of all counts, which is ideal for PGO — the compiler has strong branch/layout optimization targets.
+3. **Fortran numerical kernels dominate**: `polint_`, `prolong3_`, `compute_rhs_bssn_`, `symmetry_bd_`, `lopsided_` are all Fortran routines in the inner evolution loop. PGO will optimize their branch prediction and basic block layout.
+4. **91.6% of functions have zero counts**: These are code paths for unused features (GPU, BSSN-EScalar, BSSN-EM, Z4C, etc.). PGO will deprioritize them, improving instruction cache utilization.
+5. **Profile is representative**: Despite the reduced grid size, the code path coverage matches production — the same kernels (RHS, prolongation, restriction, boundary) are exercised. PGO branch probabilities from this profile will transfer well to full-scale runs.
+
+## 7. PGO Phase 2 Usage
+
+To apply the profile, use the following flags in `makefile.inc`:
+
+```makefile
