feat(A.5 T23): BUDGET_OVER flag in [WB-DIAG] / [TERRAIN-DIAG]

Browse source 
Per Phase A.5 spec §2 acceptance criterion 6: entity dispatcher median
≤ 2.0ms; terrain dispatcher median ≤ 1.0ms at standstill. When the
median exceeds the budget, prefix the DIAG line with " BUDGET_OVER" so
the regression is grep-friendly during perf testing.
