PR Review: Correctly test inputs in expect_setequal()

• Read and analyze the changed files
• Review the code changes for potential bugs or issues
• Provide concise feedback

Analysis of changes:

• Fixed check_vector() calls in expect_setequal() to validate act$val and exp$val instead of object and expected
• Added proper error_arg parameters for better error messages
• Added test cases for unquoted expressions using !!fun syntax
• Generated corresponding snapshot tests

Review:
The fix correctly addresses the issue where expect_setequal() was validating the wrong objects. Previously it validated object and expected (the expressions), but should validate act$val and exp$val (the actual values). This ensures proper type checking and error reporting.

LGTM.
