Replace the custom encrypted container with AgeSwift 0.1.0 so standard
age tools can inspect sensitive configuration independently of the app.
Use independent Keychain X25519 identities for catalog.age and
proxy-listening.age. Preserve atomic commits and confirmed recovery;
reject historical NG2 formats without migration or cleanup.
CatalogEntry gains createdAt/updatedAt and the catalog document moves to
v5 (reads v1-v5, writes v5). Modification time is structure-sensitive:
editing a node's own fields bumps the node, a group's direct child set
or order changes bump the group, and a moved node keeps its timestamps.
No-op writes and unchanged subscription refreshes bump nothing; the
refresh rebuild compares per node, so surviving leaves keep theirs. All
times are passed in by callers as now: Date - one moment per logical
commit, the domain layer stays clock-free. Legacy documents load with
nil (unknown, never backfilled); duplicates and imports stamp fresh
times at the moment of the operation.
Semantics are recorded as glossary term 节点时间戳 and ADR 0031. No UI
in this change.
