- Added `js/nostr/nip46Queue.js` to manage concurrent RPC requests.
- Updated `Nip46RpcClient` to serialize outgoing requests, preventing "rate-limited" errors.
- Implemented exponential backoff for retries when relays reject events due to rate limits.
- Added priority levels to `sendRpc` to prioritize user actions (signing, connecting) over background tasks (decrypting).
- Verified with new unit tests in `tests/unit/nip46Queue.test.mjs`.
- Updated `Nip46RpcClient` in `js/nostr/nip46Client.js` to implement `nip04Encrypt`, `nip04Decrypt`, `nip44Encrypt`, and `nip44Decrypt` methods by calling the respective RPC methods on the remote signer.
- Exposed these encryption methods in the `activeSignerCache` object returned by `getActiveSigner()`.
- This ensures that functions relying on encryption (like `StorageService` unlocking and DM decryption) work correctly when logged in via NIP-46.
- Simplified `components/login-modal.html` to center the QR code and use a "Copy Link" button instead of a large textarea.
- Updated `js/ui/loginModalController.js` to support the new DOM structure and error handling.
- Added `docs/nip46-roadmap.md` to document current state and future features.
- Fixed `NostrClient.destroy()` usage (synchronous void method) in `js/nostr/client.js`.
- Relaxed NIP-46 `connect` response validation in `js/nostr/client.js` and `js/nostr/nip46Client.js` to accept "ack" (case-insensitive) as a valid success signal, preventing timeouts with signers that do not echo the secret.
