Johnathan Corgan 7463d8799a Promote 27 hardcoded constants to configurable parameters ...

Add 9 config subsection structs (LimitsConfig, RateLimitConfig,
RetryConfig, CacheConfig, DiscoveryConfig, TreeConfig, BloomConfig,
SessionConfig, BuffersConfig) under node.* with serde defaults.

Wire all configurable values through to consuming code:
- Resource limits (max_connections, max_peers, max_links, max_pending_inbound)
- Rate limiting (handshake_burst, handshake_rate, handshake_timeout_secs)
- Retry/backoff (consolidate max_retries, base_interval_secs under
  node.retry.*, add max_backoff_secs)
- Cache sizes/TTL (coord_size, coord_ttl_secs, route_size)
- Discovery (ttl, timeout_secs, recent_expiry_secs)
- Spanning tree (root_refresh_secs, announce_min_interval_ms,
  parent_switch_threshold)
- Bloom filter (update_debounce_ms)
- Session/data plane (default_hop_limit, pending_packets_per_dest,
  pending_max_destinations)
- Internal buffers (packet_channel, tun_channel, dns_channel)
- Network internals (base_rtt_ms, tick_interval_secs)
- DNS responder TTL (dns.ttl)

REPLAY_WINDOW_SIZE kept as compile-time constant (array sizing).
Disable flaky test_discovery_100_nodes (run with --ignored).
