Key design: - 512-byte packed histogram (128 × 4-byte Record entries) embedded in a new HopScalingModule. - Each Record: 16-bit node hash, 3-bit hop distance, 13-bit seen bitmap - Sampling filter: only nodes where (hash & (denom-1)) == 0 are kept; denominator doubles on overflow and halves when utilisation is low - Hourly rollHour(): tallies per-hop counts, walks scaled buckets to find the minimum hop satisfying TARGET_AFFECTED_NODES (40), applies a politeness extension based on recent/older activity ratio, shifts all seen bitmaps, and persists state to /prefs/hopScalingState.bin - Hop recommendation gated by bootstrap (requires >=1 rollHour before overriding HOP_MAX) - NodeDB calls samplePacketForHistogram() on every non-MQTT rx packet - Module also estimates total mesh size and logs useful information about mesh characteristics.

Small flash size reduction, no functional impact. * Update unit test preprocessor directives to PIO_UNIT_TESTING for consistency * refactor: improve test output organization and clarity in hop scaling tests --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
