KKRainbow c01e2baafa perf(core): cap shards in per-network and per-peer maps (#2685) ...

Public relays create many mostly empty maps for each foreign network.
DashMap defaults to 128 shards on a 24-CPU host, allocating about
1.26 GiB of shard arrays for 2,421 networks before peer/session state.

Cap these maps at eight shards and retain the four-shard default on
single-CPU hosts. Cache the shard count once and keep global indexes
on their existing default. Apply the same cap to peer connection maps
and route synchronization version maps.

Replace nested peer/network DashSets with HashSets protected by their
existing outer map or an entry mutex. Keep cross-index updates under
the manager lock. Use a plain HashMap for the local route graph index.

Validation: 245 peer/RPC tests and eight three-node integration tests
passed, along with workspace fmt and clippy with full features.
