SAPDatasphereMCP

Cut a new version of the SAP Datasphere MCP server — bump the version in pyproject.toml, sync CHANGELOG.md and README, and prepare the release commit. Use when asked to release, cut a version, or bump the version.

Scaffold a new SAP Datasphere MCP tool across all four required layers (client method, business-logic function, @server.tool wrapper, example + test) following project conventions. Use when adding a new datasphere_* tool.
