Changes analyzed:

• Added tolerance = testthat_tolerance() parameter to expect_waldo_equal_() call in expect_mapequal() (line 112)
• Added new test case to verify integer/numeric differences are ignored

Review:

LGTM. The change correctly restores the tolerance behavior that was lost when reverting PR #2150.

The addition of tolerance = testthat_tolerance() ensures expect_mapequal() ignores integer/numeric differences (like 1L vs 1) in edition 3, maintaining consistency with expect_equal(). The test case appropriately validates this behavior.
