Add dynamic HTTP seed discovery, remove hardcoded seeds (v5.5.0)
Replace all hardcoded seed addresses (onion, clearnet, DNS) with a
dynamic HTTP-based seed list fetched from seeds.cryptographic-triangles.org
on startup. New getseedlist RPC exposes known .onion peers from the
address manager for a collector script to publish.

Any wallet that comes online with an onion address is automatically
discovered by peers via P2P addr exchange and appears in the seed list
within minutes. No binary rebuilds needed when addresses change.
