Publish service for the opt-in NIP-71 mirror (kind 34235/36) to the user's
write/outbox relays, built on the Phase 0 builder. Flag still off; not yet wired
into the publish path (next increment).
- js/services/nip71MirrorService.js: createNip71MirrorService (DI) → isAvailable,
canMirror(video), publish(video, options). Signs with the active signer and
publishes to the write set (getDeletePublishRelays). Resolves the moderation
audit item: the site ALLOW_NSFW_CONTENT gate — an instance that won't surface
NSFW must not publish it outward (enforced in both publish() and canMirror(),
defense-in-depth). Private/url rules come from the builder.
tests/nip71-mirror-service.test.mjs: publishes a public video; NSFW blocked when
ALLOW_NSFW_CONTENT=false (and allowed when true); private/url-less refused;
unavailable without signer. Mutation-verified (NSFW gate load-bearing).
