- Added support for resolving nested properties and arrays in expressions, including POCOs, ExpandoObject, IDictionary, arrays, lists, and JSON objects. - Introduced new context prefixes (`Input.`, `Output.`, `Variable.`, `Activity.`, `Execution.`, `Workflow.`) for accessing specific contexts and their nested properties. - Deprecated older prefixes (`Variables.`) and certain keys (`Workflow.Definition.Id`, etc.), providing updated alternatives. - Improved error handling for missing properties, invalid indices, and unsupported types. - Updated README to document new features, provide examples of enhanced expression syntax, and guide migration from deprecated keys. - Strengthened SQL injection protection by extending support for nested properties and complex objects. - Refactored `ResolveValue` for better readability and maintainability.
Refactored the `ResolveValue` method in `SqlEvaluator.cs` to use a `switch` expression with `case` patterns, improving readability and maintainability. Replaced deprecated hardcoded expression keys with updated keys to align with the new expression model. Updated `README.md` to document the new expression syntax, including examples for accessing `Input`, `Output`, `Variable`, and nested properties. Highlighted breaking changes in version 3.6.0 and provided guidance for transitioning from deprecated keys.

Closes #85
Activity.,Execution.,Workflow.) for accessing specific contexts and their nested properties.Variables.) and certain keys (Workflow.Definition.Id, etc.) as deprecated. Providing updated alternatives.Breaking Expression Changes
As the evaluator can now use workflow properties directly, the previous hard coded expression keys have been be removed.
To access the previous key values you will need to update your expressions.
{{Variables.<VariableName>}} --> {{Variable.<VariableName>}} {{Workflow.Definition.Id}} --> {{Workflow.Identity.DefinitionId}} {{Workflow.Definition.Version.Id}} --> {{Workflow.Identity.Id}} {{Workflow.Definition.Version}} --> {{Workflow.Identity.Version}} {{Workflow.Instance.Id}} --> {{Activity.WorkflowExecutionContext.Id}} {{Correlation.Id}} --> {{Activity.WorkflowExecutionContext.CorrelationId}}
