Describe the bug
When running the test with ASan enabled, it reports a lot of memory leaks.

To Reproduce
Steps to reproduce the bug:

0. install clang-20 to build the project as documented in the librime-qjs project.
1. make clean
2. make debug CFLAGS="-g -fsanitize=address" LDFLAGS="-fsanitize=address"
3. cd debug/test
4. ASAN_OPTIONS=detect_leaks=1 ./rime_test > rime_test.leak.log 2>&1

Expected behavior
There should not be any memory leak issue reported in running the tests.

Additional context
With the Squirrel frontend in the same system, it seems the memory leak problem does not happen in the built librime.dylib.
I guess there could be something wrong in the test setup code.
