Supernode: Faster Processing with Backoff

[axelKingsley]

What

Adaptive tick rate for interop activity

• Lowered tickerPeriod from 500ms → 50ms for fast progress when data is available
• Added backoffPeriod (1s) when chains aren't ready, preventing busy-waiting
• Extracted the error sleep into errorBackoffPeriod (2s) for clarity
• progressAndRecord(): Now returns (verifiedAdvanced bool, err error) to signal whether the verified timestamp was advanced, driving the backoff decision
• Unit tests now assert advancement
