Clear environment variable when initializationProcedure is no longer set

[kenherring]

Fixes #494

[Copilot]

Pull request overview

Fixes a regression where initializationProcedure could continue to be used after being removed from the test profile by explicitly clearing the related environment variable, and improves runner-side handling when an initialization procedure can’t be located.

Changes:

• Clear ABLUNIT_INITIALIZATION_PROCEDURE when no initializationProcedure is configured.
• Add an ABL-side search() check and throw a clearer error if the initialization procedure isn’t found.
• Bump extension version and update changelog entries.
