Csaba Kiraly 5a918be50d eth: protect high-value peers from random dropping based on inclusion stats
The dropper periodically disconnects random peers to create churn.
This was blind to peer quality. Add inclusion-based peer protection
using two categories:

1. Total inclusions: protects peers with the highest cumulative
   count of delivered txs that were included on chain
2. Recent inclusions (EMA): protects peers with the best recent
   inclusion rate, giving newly productive peers faster protection

Each category independently protects the top 10% of inbound and
top 10% of dialed peers. The union of both sets is protected. Only
peers with positive scores qualify.

The dropper defines its own PeerInclusionStats struct and callback
type (getPeerInclusionStatsFunc) so any stats provider (e.g. a
transaction tracker) can plug in without a package dependency. The
callback is nil by default (protection disabled until wired).

The protectionCategories slice is designed for easy extension —
adding a new category requires only appending a struct with a name,
scoring function, and protection fraction.
