🐛 Bug Fixes

• Fix spray undo regression: preserve CheckTiles across spray ticks

• Remove per-tick generation increment in SprayAtPoint that was resetting
  the dedup state, causing already-painted tiles to be re-saved to undo
  with their modified state (corrupting undo) and re-painted redundantly

• The generation set in MouseDown now persists across the entire spray
  stroke, so each tile is only saved to undo and painted once

• Fix flood fill skipping leftmost tile column (x=0)

• Change boundary check from lFillLoc <= 0 to lFillLoc < 0 so the
  leftward scan processes x=0 instead of stopping one tile early

📦 Other Changes

• Brush performance optimization: cache, buffers, generation counter

• Cache brush shape offsets in BrushSettings, translate on stamp instead of
  recalculating geometry per interpolation point (~70-85% CPU reduction)

• Move ThickenLine/ErodeShape to BrushSettings as public static helpers

• Pre-allocate stamp/line/sweep buffers in BrushToolBase to eliminate
  per-frame List/HashSet allocations

• Replace bool[] CheckTiles + Array.Clear with int[] + generation counter
  to skip 20MB clear on each stroke start

• Update all tool files (Pencil, Morph, Sprite, Fill, Hammer, DrawApi,
  WorldEditor) to use generation-based dedup pattern

• Texture loading message
