i386: wmc_tool Python tests fail in 32-bit container

[ludomal]

Summary

Two wmc_tool tests fail on the i386 (32-bit) CI job. All other 1335 tests pass.

Failing tests

• wmc_tool_test_multiple_files
• wmc_tool_test_rom_file2

Environment

• Debian i386 container via QEMU
• Python3 available

Likely cause

Shell glob expansion or path handling difference in the 32-bit container environment. The same tests pass on all other platforms (Ubuntu 64-bit, macOS, Windows).

Context

Identified during STL2026 CI validation (PR #190). Non-blocking for release but should be resolved for the next update.
