Subject: [PATCH] revert(ci): remove RAM disk experiment from Windows CI

RAM disk approach proved insufficient for Windows test speedup:
- t.Chdir() panics on ImDisk drives
- Temp-only RAM disk provides marginal improvement (~50%)
- Still times out at 30 minutes

Reverted to simple Windows tests with continue-on-error.
Created bd-bmev to replace with smoke tests instead.
Closed bd-5we as RAM disk approach didn't work.
