Add support for expose parameter #1744

What would you like?

• Add the ability to accept an expose parameter as input to the action.
• Demonstrate and test the parameter in CI, either in .github/workflows/example-env.yml or in a separate workflow.

Why is this needed?

The Cypress Module API added the Option expose in cypress@15.10.0 in Feb 2026.

This is not available as a parameter in the action at this time.

--expose was also added as a CLI option at the same time

See:

• action.yml
• CLI Run Option / Action Parameter
