### Motivation
- Prevent a browser-policy muted-autoplay retry from overwriting a viewer's explicit mute/unmute preference and ensure fallback mutes are transient.
- Ensure that when a user logs in while a video comment modal is open, the open thread is reloaded (not just refreshed) so comments continue to display correctly after relay-backed services are reconfigured.
### Description
- Add `js/utils/autoplayPreference.js` with `muteForAutoplayFallback` and `consumeAutoplayFallbackMute` helpers to mark and consume transient fallback mutes.
- Update `js/services/playbackService.js` to treat sound as default unless the viewer explicitly chose mute, persist explicit choices via `localStorage`, ignore fallback-generated volume changes using `consumeAutoplayFallbackMute`, and expose `muteForAutoplayFallback` delegating to the new util.
- Replace direct `videoElement.muted = true` calls with `playbackService.muteForAutoplayFallback` in `js/app/playbackCoordinator.js` and `js/webtorrent.js` so fallback mutes are marked as transient.
- Change `js/app/authSessionCoordinator.js` to reload the currently open video comment thread with `commentController.load(activeModalVideo)` after login if a modal video is active, instead of only calling `refreshAuthState`.
- Update tests in `tests/services/playbackService.test.mjs` and add a test in `tests/app/login-defers-dms.test.mjs` to cover the login behavior that reloads an open comment thread.
### Testing
- Ran the `PlaybackService` unit tests (`tests/services/playbackService.test.mjs`) which assert `prepareVideoElement` behavior, explicit mute persistence, and the transient nature of fallback mute, and they passed.
- Ran the auth login unit tests including `tests/app/login-defers-dms.test.mjs` which verifies DM deferral and reload of an open comment thread, and they passed.
(cherry picked from commit ce14004725)
The For You feed was chronological, hashtag-interest-EXCLUSIVE, and ignored
follows entirely (docs/feed-algo-audit.md). Now it is inclusive + ranked:
- createForYouScorerStage scores each video: follows-boost (author you follow)
+ interest/watch-topic affinity (cosine vs your interests+watch-history vector)
+ freshness - disinterest penalty. Reuses Explore's vector/similarity helpers.
- createForYouScoreSorter ranks by that score (muted last, recency tiebreak).
- For You pipeline: interests now BOOST not exclude (enforceInterests:false);
scorer added; chronological sorter replaced. Never empty (falls back to
recency when you have no follows/interests/history).
- buildForYouFeedRuntime now feeds subscriptionAuthors + watchHistoryTagCounts.
Watched/blocked/muted are still removed (suppression/blacklist/moderation
stages unchanged). Cheat-resistant tests (older boosted items only win via the
boost). Grid renders end-to-end (~1.3s). Weight tuning is a follow-up.

- Deleted `js/magnet.js` as it was a redundant wrapper for `js/magnetUtils.js`.
- Refactored `js/services/videoNotePayload.js`, `js/ui/components/EditModal.js`, and `js/nostr/nip71.js` to use `magnetUtils.js` and `magnetShared.js`.
- Updated `tests/magnet-utils.test.mjs` to remove tests for the deleted file.
- Removed unused exports `DEFAULT_FEED_CONFIG` and `DEFAULT_CONFIG_SCHEMA` from `js/feedEngine/engine.js` and `index.js`.
- Verified changes with unit tests.
