Subject: [PATCH 1/4] docs: align development docs with codebase behavior

Updates documentation to match current codebase implementation:
- Deprecates `nostrClient.fetchVideos` in README.md, pointing to `subscribeVideos`.
- Clarifies `playVideoWithFallback` implementation location in `docs/playback-fallback.md` and `AGENTS.md` (moved to `js/app/playbackCoordinator.js`).
- Corrects `WATCH_HISTORY` d-tag description in `docs/nostr-event-schemas.md` to match actual code behavior (`<YYYY-MM>`).

Prefer to publish both along with optional `thumbnail`, `description`, and `mode` fields. When mirroring to NIP‑94 (`kind 1063`), copy the hosted URL and (optionally) the magnet so other clients can discover the same asset.

+The `nostrClient` uses `subscribeVideos(callback, options)` for the main feed to support buffering and streaming. It accepts an optional `options.limit` to control how many video events are requested per relay. The request size defaults
 to `DEFAULT_VIDEO_REQUEST_LIMIT` (150) and is clamped to
 `MAX_VIDEO_REQUEST_LIMIT` (500) to avoid accidental firehose requests as the
 network grows. Use a smaller limit for lightweight surfaces or a larger value

 3. Playback starts with the hosted URL when `URL_FIRST_ENABLED` is true and a URL is available; otherwise, it goes directly to torrent playback.
 4. If URL playback stalls or errors, the session triggers `playViaWebTorrent` with the normalized magnet and optional web seed hints.

Subject: [PATCH 2/4] fix(nostr): duplicate 'extension' declaration in
 SignerManager

Fixes a SyntaxError in SignerManager.js where `extension` was declared twice in the same scope. This resolves CI failures in tests depending on SignerManager.

Subject: [PATCH 3/4] fix(nostr): implement missing resolveEventDTag in
 NostrClient

Added the `resolveEventDTag` method to the `NostrClient` class in `js/nostr/client.js`. This method was referenced in `editVideo` and `hydrateVideoHistory` but was missing from the implementation, causing `TypeError` in tests. The implementation delegates to `getDTagValueFromTags` from `js/nostr/nip71.js`.

Subject: [PATCH 4/4] 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.
