docs: adapt to Palladium, drop Bitcoin/upstream examples and links

index, features, HOWTO (node requirements, sizes and sync time measured on
Palladium, real startup log, clone URL), environment, peer discovery and
architecture; rpc-interface examples (getinfo, peers, query with real data);
release_process rewritten without tags/PyPI; changelog gets a plm-electrumx
1.0.0 entry above the upstream history. Links point to this repository.
