Python reset tests use stale _native.pyd in repo checkout

[zackees]

The ESP32-S3 reset integration is blocked in a clean checkout because python/fbuild/_native.pyd is stale relative to crates/fbuild-python/src/lib.rs.

Repro on the attached COM13 board:

1. cargo build -p fbuild-python
2. python -m pytest tests/test_serial_reset.py -q
3. The import resolves to python/fbuild/_native.pyd, which in this checkout does not expose SerialMonitor.reset_device.
4. If I stage the fresh target/debug/_native.dll into a temp package and rerun, the method exists and the HTTP reset returns success.

Observed behavior:

• Plain python -m pytest tests/test_serial_reset.py -q fails with ModuleNotFoundError or AttributeError depending on the import path.
• The repo docs imply the Python package should re-export the Rust _native extension, but the checked-in binary is out of sync with the source.

This blocks physical-board validation unless the package is rebuilt/installed first.
