Why: GET /api/conversations on the default unarchived view appended
AND archived=0. PostgreSQL stores conversations.archived as BOOLEAN
and rejects boolean = integer (42883), so listTasks returned 500.
The previous dialect fix bound parameters and scans but left this literal.
Evidence: before the change, TestConversationFlagsAndTaskList against
pg1 failed with SQLSTATE 42883. After: AGENT_PG_TEST_DSN set to pg1,
go test ./internal/store -count=1 passed; go vet ./... && go test ./...
passed on SQLite.
Impact: the default task list works on the postgres tier. SQLite still
binds the bool as 0/1. openTestStore accepts URL and keyword DSNs and
keeps public on search_path so an existing pg_trgm extension stays visible.
