fix: Align development docs and fix SignerManager v2 compatibility

- Aligned `README.md`, `AGENTS.md`, and `docs/` with codebase reality.
- Fixed `ReferenceError` in `js/nostr/managers/SignerManager.js`.
- Implemented missing `resolveEventDTag` in `js/nostr/client.js`.
- Updated `SignerManager.js` to support `nostr-tools` v2 `generateSecretKey` and handle `generatePrivateKey` aliasing (returning `Uint8Array`).
- Updated `js/nostr/publishHelpers.js` to support `finalizeEvent` (v2) by converting hex keys to bytes.
- Updated `js/nostr/sessionActor.js` to correctly identify session actor context, allowing authenticated users to publish watch history.
- Fixed `tests/nostr/integration-remote-flow.test.mjs` by ensuring `generateSecretKey` is mocked.
