- Replace single localStorage string with versioned multi-domain store
(fediverse_domains_v1) with usage tracking, inspired by Mastodon's
share.joinmastodon.org project
- Add domain validation via URL constructor before redirecting
- Add mode param to fediverseInteract component: "interact" for
authorize_interaction, "share" for /share?text=...
- Migrate old fediverse_instance key automatically on first load
- Extract shared modal partial (fediverse-modal.njk) used by post
interaction, follow widget, and share widget
- Share widget now prompts visitors for their own instance instead of
hardcoding site owner's Mastodon instance
