chore: replace btsm with tsm

[chenjiahan]

Summary

The btsm package was forked from tsm to add support for dynamic import, now tsm has added the official support, so we can switch back to `tsm.

🤖 Generated by Copilot at d3cc4d1

Updated the testing and scripting dependencies to use tsm and tsx packages that support TypeScript 4.5 and ESM modules. Renamed and modified the test files and scripts accordingly.
