- Replaces median-based classification with 75th percentile for 'Authority' and 'Hub' roles - Adds new `hits_precision.test.ts` to verify distribution (~25% high-tier nodes) - Updates `hits.test.ts` to use a slightly larger graph for stable classification - Improves comments in `hits.ts` to match implementation logic This aligns the HITS algorithm with the intended "high-tier" definition, reducing noise in large graphs where median classification was too broad.

This PR improves the precision of the HITS (Hyperlink-Induced Topic Search) algorithm in
@crawlith/core. Previously, the implementation used a median (50th percentile) threshold to classify nodes as "Authority" or "Hub", which resulted in too many nodes being labeled as high-importance (~50-80%).This change updates the logic to use a strict 75th percentile threshold, targeting the top ~25% of nodes, which better aligns with the concept of "elite" or "high-value" pages in a link graph.
