* fix(managed-subagents): make signature() change when an update lands in one clock tick SqlManagedSubagentStore.signature() returns the tuple of (id, updated_at), so a definition change is only visible to peer processes when the row's stamp moves. The ORM onupdate callback reads the wall clock, which has ~15.6 ms resolution on Windows and can also sit behind a stamp written by a node with a skewed clock. In both cases the new value equals or precedes the stored one and the registry snapshot is never invalidated. Force updated_at strictly forward in update(): normalise SQLite's naive datetime to UTC and, when the clock has not advanced past the stored value, bump it by one microsecond. Add a regression test that freezes both clocks to the stored timestamp; it fails without the fix (signature unchanged) and passes with it.
