Final NDK removal (follow-up to #44/#45). The standalone CLI (src/client.ts)
was the last NDK user — a NIP-46 *client* (NDKNip46Signer). Ported to a small
nostr-tools client so the dependency can leave the repo completely.
- src/nip46-client.ts — a minimal NIP-46 client over the RelayPool, the inverse
of the daemon's Nip46Transport: send requests to a remote signer, match
responses by id, surface auth_url prompts; nip44 envelope. Methods: connect /
signEvent / createAccount.
- src/client.ts — rebuilt on it. nip05/npub/bare-domain resolution via
nostr-tools nip05.queryProfile + nip19; local client key stored as hex;
publish via the pool. Dropped the now-unused websocket-polyfill import.
- package.json + pnpm-lock.yaml — `@nostr-dev-kit/ndk` removed (and its orphaned
transitive deps; lockfile reconciled with `pnpm install --lockfile-only`, no
version-format change).
`grep -r @nostr-dev-kit/ndk src` is now empty; all three bundles (index, daemon,
client) build with 0 NDK references. Tests: lifecycle 7 / relay 2 / nip46 1 /
admin 2 green; tsc at the pre-existing baseline.
