Strengthen is_connected with cached health probes.

Connection adapters expose `connect()`, `disconnect()`, and `is_connected()`. The latter verifies backend reachability with a cached health probe (default TTL: 1 second). Subclasses may override `health_check_ttl_seconds`.

Repository **interfaces** import with the base package. **Adapters** require the matching extra; importing an adapter without its extra raises `ImportError` with install instructions.
