v3.2.0

Minor Changes

• Chained/dependent variables support - Variable queries now support template variable interpolation using ${variable} syntax, enabling powerful cascading variable dependencies. Users can now create hierarchical variable relationships (e.g., Zone → Location → Sensor) where selecting a value in one variable automatically filters options in dependent variables (see Variables documentation). (issue #182) - Thanks @HadesArchitect
• Query mode switcher - Improved mode-switching UI replacing the plain "Toggle editor" with a RadioButtonGroup (Configurator / Query Editor) for a better UX.

Patch Changes

• Improved UI with contextual documentation links - Linked relevant docs page (configurator or editor) and GitHub Discussions for Query Editor, Variable Editor and Configuration page.
• Added support for Cassandra VARINT columns (#235) - Querying a table with a varint column caused the plugin to crash with field value has unsupported type *big.Int. Cassandra's varint type is an arbitrary-precision integer backed by Go's *big.Int, which was not handled during row normalisation. The fix adds explicit conversion of *big.Int values so that varint columns are returned as numeric data instead of producing an error. (issue #235) - Thanks @HadesArchitect and @arturngomes
• Fix ConfigEditor - stop mutating React props directly instead of using proper state updates (issue #230) - Thanks @hugohaggmark
