💡 What: Refactored TelemetrySystem to use a circular array (ring buffer) instead of standard array push() and shift() operations.
🎯 Why: In high-frequency recording loops (like the telemetry data), using Array.prototype.shift() when the buffer exceeds its maxDataPoints causes an O(N) array re-indexing operation, leading to performance degradation and high garbage collection pressure.
📊 Impact: Expected to reduce execution time for telemetry shifting/updating significantly by converting O(N) shift operations to O(1) modulo index assignments. In benchmark tests (benchmark_telemetry.ts and benchmark_telemetry_stress.ts), it shows an improvement in time per operation for worst-case buffer shifting.
🔬 Measurement: Verify by running tests/benchmark_telemetry_stress.ts. Time per iteration should remain stable in O(1) instead of degrading linearly. All telemetry UI and tests should continue to pass normally.

Replaced `Array.prototype.push()` and `Array.prototype.shift()` with a circular array and `dataHead`/`dataCount` pointers to eliminate O(N) shift operations and reduce garbage collection pressure.
