Enhancement: Hardware Binding Weighted Scoring

[MichaelSovereign]

Summary

This PR improves the stability of the hardware fingerprint similarity calculation by introducing field-specific weighting.

Changes

1. Weighted Metrics: Defined a map where stable hardware characteristics (like L1/L2 cache latencies) have significantly more influence on the final similarity score than volatile metrics (like clock drift or instruction jitter).
2. Robust Comparison: Ensures that the system is less prone to false positives caused by temporary system load or ambient temperature changes while remaining sensitive to actual hardware swaps or spoofing attempts.
