feat(prototype): 2D swarm data-plane visualization

Top-down SVG view: patrol flight with separation and obstacle avoidance,
mesh links appearing within radio range, pose-broadcast flashes, bulk
sync transfers with live rate and cumulative up/down counters, channel
hopping and battery per drone. Pure client-side simulation (Vite/React/TS).
