Mueve duckdb_open, clickhouse_open, postgres_open, matrix_* y keyring_token_store
del paquete monolitico functions/infra a subpaquetes propios
(functions/infra/{duckdb,clickhouse,postgres,matrix,keyring}). El paquete infra ya
no importa los drivers (go-duckdb, clickhouse-go, pgx, mautrix, go-keyring), por lo
que las apps que solo usan funciones ligeras (process, cron, http, sqlite) dejan de
arrastrarlos. Reduccion de binarios: dag_engine 72->10MB, registry_api 70->8.7MB,
services_api 70->9MB, call_monitor 68->6.6MB, sqlite_api 70->8.9MB.
Los IDs del registry se mantienen estables (domain: infra en frontmatter). Se
preservan los build tags goolm/libolm de matrix_crypto_init.
Tambien corrige TestSSEHandler: el test leia el body con un unico Read() que con
HTTP chunked solo capturaba el primer evento; ahora usa io.ReadAll hasta EOF.

## Ejemplo
|
|
|
|
```go
|
|
db, err := ClickHouseOpen("localhost", 9000, "default", "", "analytics")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer DBClose(db)
|
|
|
|
rows, err := DBQuery(db, "SELECT event, count() FROM events GROUP BY event")
|
|
```
|
|
|
|
## Notas
|
|
|
|
Usa el driver `github.com/ClickHouse/clickhouse-go/v2` registrado como "clickhouse". Puerto por defecto de ClickHouse es 9000 (nativo) o 8123 (HTTP). Hace ping al abrir para verificar conectividad.
