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。

perf(restrict3): shrink X-pass ii sweep to required overlap window
...
- compute fi_min/fi_max from output i-range and derive ii_lo/ii_hi
- replace full ii sweep (-1:extf(1)) with windowed sweep in Z/Y precompute passes
- keep stencil math unchanged; add bounds sanity check for ii window
