New Features and Enhancements

Added a new rai config:explain command to inspect the active configuration and where each value came from. Now you can inspect the active config directly from the CLI and optionally show full provenance details with --verbose:
Terminal window
```
rai config:explain
rai config:explain --verbose
```
Improved dtype inference for pandas columns with object dtype when PyRel derives concept types from data. PyRel now does a better job recognizing numbers in pandas object columns. For example, if a column contains decimal values, PyRel now treats it as numeric instead of treating it as text.

Fixed an issue with rai connect where invalid Snowflake warehouse names could pass basic connectivity checks. The command now validates the configured warehouse.
Fixed a bug that caused select() to raise a ValueError when selecting a Match object.
Fixed a bug where PyRel would warn about graph validation whenever you selected a Graph.Edge entity. You can now select or inspect Graph.Edge without triggering validation warnings. PyRel waits to validate until you run a graph operation that actually needs it.
Fixed a bug that could cause the client to get disconnected during long-running graph algorithms or other work if a jobs polling attempt was delayed or missed. The maximum polling delay is now short enough to prevent accidental disconnects from transient polling issues.
Fixed a bug that could affect results in some queries involving values that could match multiple types.
