refactor(store): extract agent session/trust methods from sqlite.go

Pure move: all agent-session and agent CRUD/trust methods (~340 lines)
plus their full test suite and setupTestStoreWithAgents helper, out of
sqlite.go/sqlite_test.go into agents.go/agents_test.go. No behavior
change. Mirrors internal/handlers/agent.go's domain naming.
