Frooty magical sparkle visual effects

**Character:** Frooty (Character 8)

**Enhancement Request:** Add magical sparkle particle effects to Frooty's ranged attack projectile for visual polish.

**Current Status:** Frooty's ranged attack is functional but lacks the magical sparkle effects described in the manual: "Use your lollipop weapon's magical sparkles for ranged combat"

**Requirements:**

### Visual Enhancement Only
- Add cosmetic sparkle particle effects to Frooty's projectile
- Multi-sparkle pattern or sparkle trail effect
- Visual flourish for magical lollipop weapon
- Does not affect gameplay mechanics

**Implementation Notes:**
- This is a visual-only enhancement (not gameplay mechanic)
- Frooty projectile functionality is already implemented
- May require sprite overlay or particle system
- Character selection screen may show sparkle preview

**Files Likely Affected:**
- Source/Routines/MissileSystem.bas (sprite rendering)
- Source/Routines/MissileRendering.bas (if exists)
- Character sprite data for sparkle overlays

**Dependencies:**
- Frooty sprite art and animation
- Particle/overlay sprite system
- Visual effects rendering pipeline

**Priority:** Low - cosmetic enhancement, not functionality blocking
