Subject: feat(v2.0.0): introduce tracked domains, diffing, and monitoring
 foundations

- replace basic watchlist with structured TrackedDomain model
- add manual refresh flow for tracked domains
- implement snapshot diffing (DNS, IP, TLS, HTTP, redirect, email, availability)
- add change summaries (changed/unchanged + affected sections)
- link tracked domains to history snapshots
- enhance HistoryEntry with normalized summary fields
- persist availability + suggestions in history and export
- add WatchlistView with pinning, notes, and status display
- introduce premium capability scaffolding (no StoreKit)
- enforce free-tier tracked domain limit (local only)
- refactor view model to support tracking, diffing, and refresh flows

notes:
- no background monitoring, notifications, or paid APIs yet
- all features remain local-first and manual
