"""
T2.4: Parameter Templating and Context

Tests that actions can use Jinja2 templates to access execution context,
including trigger data, previous task results, datastore values, and more.

Test validates:
- Context includes: trigger.data, execution.params, task_N.result
- Jinja2 expressions evaluated correctly
- Nested JSON paths resolved
- Missing values handled gracefully
- Template errors fail execution with clear message
