v2.0.0

Atomic add/remove with scoped commits, default linking/restoration, recovery,
routine Git synchronization and compact, actionable status observations.

Breaking changes: remove replaces the old unlink alias, update without a URI
synchronizes the active repository, explicit empty collections select no defaults,
and status reports nullable facts with successful exit for completed host reports.
The Go module is gitlab.com/pidrakin/dotfiles-cli/v2.

Includes Go 1.26.8 and golang.org/x/crypto 0.56.0 security fixes.
