ci(windows): use shell: pwsh (PowerShell 7) — fixes GITHUB_ENV BOM corruption

Browse Source 
Windows PowerShell 5.1's Out-File -Encoding utf8 prepends a UTF-8 BOM, corrupting the first
GITHUB_ENV line so CARGO_WORKSPACE_DIR silently never got set -> windows-reactor build.rs panic
-> CI build failed (runs 8765/8768). pwsh 7 writes UTF-8 without a BOM. Installed PowerShell 7.6.2
MSI on the runner and put C:\Program Files\PowerShell\7 on the daemon wrapper PATH so jobs find
pwsh; switched all windows.yml steps to shell: pwsh. (Reproduced locally with CARGO_WORKSPACE_DIR
set: the build is green in 2m37s — the BOM was the only issue.)
