Can't yet remove is_informative_error() because vctrs still registers methods for it.

Review

The changes look clean and properly advance deprecations:

1. expect_snapshot_file(binary): Correctly upgraded from lifecycle::deprecate_soft() to lifecycle::deprecate_warn() in R/snapshot-file.R:140. This is the expected progression for deprecation lifecycle.

2. test_dir(wrap) removal: Properly removed the deprecated parameter and all associated code from:

   • Function signatures
   • Parameter validation logic
   • Documentation

The implementation is consistent across all affected functions (test_dir(), test_files(), test_files_serial()). Documentation updates match code changes.

LGTM - no bugs or issues identified.
