chore(release): bump full-node to 2.1.0 and lite to 2.0.0

Full node 2.0.2 -> 2.1.0 (minor): a large additive feature + audit-fix release
since v2.0.2 with no breaking changes and only opt-in/user-initiated migrations.
Lite 1.1.1 -> 2.0.0 (major): inherits the shared feature work and carries a
deliberate on-disk/interop format change — newly-encrypted lite wallets now use
the salted Argon2id KDF (wallet v10) that older ObsidianDragonLite / SilentDragonXLite
cannot open — plus the lite line reaching functionally-complete status this cycle.

Single source of truth: project(VERSION) + DRAGONX_LITE_VERSION in CMakeLists.txt.
