fix(windows): quote Expand-Archive paths for apostrophes

[stantheman0128]

Summary

On Windows, extractZipWindows fell back to PowerShell Expand-Archive with paths embedded in single quotes via -Path. Paths containing an apostrophe (for example C:\Users\O'Brien\...) break that command, so binary/model zip extraction fails after tar fallback.

This switches to powershell.exe with -LiteralPath and doubles apostrophes for PowerShell single-quoted strings.

Verification / Evidence

node --test --test-name-pattern "PowerShell|escapePowerShell|falls back to PowerShell|falls back to JS tar|extracts a zip|unzipper" test/helpers/extractArchive.test.js
# 6 pass, 0 fail

# Live Win11 smoke: Expand-Archive -LiteralPath with O''Brien-escaped paths extracts OK
# (pre-existing corrupt-zip test still fails on Windows on origin/main; A/B confirmed)

Test plan

• Unit tests for Expand-Archive argv + apostrophe escaping
• Live PowerShell Expand-Archive with apostrophe path (escaped)
• Manual: download a zip into a user profile path that contains an apostrophe
