Adds a minimal reproducer for the `similar-content` logic bug where candidates are not correctly ordered or filtered.
This confirms the failures seen in `tests/app/similar-content.test.mjs`.
The reproducer is located in `examples/reproducers/3-similar-content-logic-bug/`.
This commit adds a minimal reproducer script that demonstrates a bug where comments on an original video are hidden when viewing that video via a Repost (Kind 6).
The issue stems from `normalizeCommentTarget` using the Repost's metadata (Kind 6, Reposter Pubkey) instead of the Original Video's metadata to generate the comment filter descriptor. This causes valid comments (which tag the Original Video) to be filtered out by `isVideoCommentEvent`.
Added:
- `examples/reproducers/2-repost-comment-visibility-bug/reproduce_issue.js`
- `examples/reproducers/2-repost-comment-visibility-bug/README.md`
- Add fuzz testing scripts for `nostrEventSchemas.js`, `dmDecryptor.js`, and `magnetUtils.js` in `scripts/agent/`.
- Fix `build...` functions in `nostrEventSchemas.js` to handle `null`/`undefined` inputs.
- Fix `buildVideoPostEvent` to gracefully handle circular references in content serialization.
- Fix `normalizeAndAugmentMagnet` in `magnetUtils.js` to handle non-iterable `extraTrackers`.
- Include minimal reproducers for discovered crashes in `examples/reproducers/`.
