feat(grid): Replace real-time CTF with turn-based grid system

Browse Source 
Replace continuous free-form movement with discrete 20x50 grid-based
gameplay featuring asymmetric movement mechanics:

- Blue/Red teams with 3 units each
- Zone-based movement: orthogonal (4 dir) in offense, diagonal (8 dir) in defense
- Alternating turns with click-to-select, click-to-move input
- Fog of war: 3-cell Chebyshev vision radius per unit
- Defense speed nerf: skip every 4th move in own zone
- AI opponent that chases flag carriers and advances toward enemy flag
- Collision resolution: defender wins in their zone, lower ID wins in neutral

Implements all 3 phases from the plan:
- Phase 1: Playable grid with hot-seat two-player
- Phase 2: Fog of war + defense speed nerf
- Phase 3: AI opponent
