Goblin P0-P3 backend: brand reskin, theme tokens, nostr payment subsystem

Infrastructure (P0): deployed nostr-rs-relay (wss://nrelay.us-ea.st) and the
goblin-nip05d NIP-05 service (goblin.st) on us-ea.st with TLS + DNS.

Brand & theme (P1): Goblin name/icon/data-dir (.goblin); three-theme token
system (light/dark/yellow) in gui/theme.rs with colors.rs remapped as a shim;
Geist + Geist Mono fonts; AppConfig theme/density/last_wallet_id.

Nostr subsystem (P2-P3): src/nostr/ with NIP-06 identity (seed-derived,
NIP-49 encrypted), per-wallet rkv archive, guarded ingest policy (never
auto-pays Invoice1; binds replies to the stored counterparty npub), NIP-17
send/receive pipeline, NIP-05 client. Relay traffic routed over the embedded
arti Tor client via a custom WebSocketTransport. Wired into Wallet lifecycle
and the task handler. 26 unit tests pass.
