Document possible async support and drop redundant pytest pythonpath.

The package is already installed via uv sync, so pytest no longer needs a manual repo-root path.

 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`. `connect()` is idempotent: calling it while already connected and healthy is a no-op.
 
+## Future direction
+
+The current API is synchronous. Async repository interfaces and adapters may be added in a future release; existing sync usage would remain supported.

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