Add comprehensive networking analytics to support peer selection based
on performance and trust metrics for KD-Tree based NAT routing:
- Add kdtree_analytics.go with TreeAnalytics, PeerAnalytics,
DistributionStats, NATRoutingMetrics, TrustMetrics, and
QualityWeights structures
- Track query/insert/delete operations with timing statistics
- Track per-peer selection frequency and average distances
- Add PeerQualityScore() for composite peer ranking
- Add ComputeTrustScore() for reputation-based selection
- Add distribution statistics (min, max, mean, median, percentiles)
- Add feature normalization helpers for multi-dimensional peer data
WASM/TypeScript integration:
- Expose all analytics via WASM bindings
- Update TypeScript definitions with full type coverage
- Update loader.js with new API methods
- Update TypeScript demo to showcase analytics features
Includes comprehensive test coverage for all analytics functionality.
This commit introduces a comprehensive test suite for the `gonum` backend, which was previously untested. It also adds tests for the `kdtree_helpers` package, specifically for the `ComputeNormStats3D` and `BuildND` functions.
The new tests cover a wide range of scenarios, including:
- Basic functionality of `Nearest`, `KNearest`, and `Radius`
- Edge cases such as empty trees, zero/negative inputs, and mismatched dimensions
- Various data configurations, including collinear points and negative coordinates
This commit also includes minor fixes to the existing tests to improve their robustness and accuracy.
As a result of these changes, the overall test coverage of the project has been increased from 80% to over 90%.
