Pull Request Overview

This PR updates the Lean4 testing and execution functionality by refining the build command, extending test coverage for the "have" tactic, and enhancing goal text aggregation for unsolved proof states.

• Added a new test method (test_simple_lean4_have_test) to validate the handling of the "have" tactic.
• Modified goal text collection in the Lean4 executor to support multiple unsolved messages.
