• perf: pre-compute tag color prefixes, eliminate per-tick string allocs
  FormatColorTag was calling FastRGB (string.format) + two concats on
  every UNIT_HEALTH and UNIT_POWER_FREQUENT tick per unit frame. Class
  and reaction color hex strings are constants — now built once at tag
  init into lookup tables. Also consolidates health percent formatting
  into a single format() call and drops a redundant tostring() in the
  Classic power percent tag.
• perf: eliminate per-tick closure allocation in gradient color updates
  Health, power, and castbar PostUpdateColor hooks called
  GenerateClosure on every invocation, allocating a new function
  object that was used once and discarded. Replace with direct method
  calls that return colorMap/colorEntry values and pass them straight
  into SetGradientColors.
• perf: replace per-frame OnUpdate with tickers and on-demand flush
  • Core event manager: replace persistent OnUpdate with E:Delay(0)
    flush, only scheduled when the queue is non-empty
  • WunderBar SecureFlyOut: replace per-frame cooldown OnUpdate with
    C_Timer.NewTicker(0.5) per slot; cancel on slot reset and hide
  • VehicleBar vigor bar: replace per-frame animation OnUpdate with
    C_Timer.NewTicker(0.05); cancel in Disable()
