Makes the NIP-71 mirror user-facing via the My Videos tab — the natural
manage-my-videos surface — without touching the single-writer publish path.
- js/constants.js: new FEATURE_NIP71_MIRROR flag (default on). Independent of
FEATURE_PUBLISH_NIP71, which is already wired to the LEGACY 21/22 auto-publish in
videoPublisher.js — flipping that would activate the wrong (non-opt-in) model, so
the opt-in mirror gets its own flag and that legacy path stays dormant.
- js/services/nip71MirrorFlags.js: per-video opt-in persistence
(pubkey+videoRootId, off by default) + pure resolveMirrorToggle decision.
- MyVideosController: per-row "Share to apps" / "Shared ✓" toggle (gated by the
flag), wired to nip71MirrorService.publish/remove. Ineligible videos show a
disabled "Share off" with the reason (private / NSFW-not-allowed-here / needs
hosted URL) — the ALLOW_NSFW_CONTENT moderation gate surfaces here too.
tests/nip71-mirror-flags.test.mjs: persistence scoping + toggle decision
(enabled→remove, eligible→publish, ineligible→blocked). Mutation-verified.
