* Fix Windows PowerShell 5.1 compatibility in installer
Use $env:PROCESSOR_ARCHITECTURE for arch detection instead of
RuntimeInformation::OSArchitecture which may not be loaded in
every Windows PowerShell 5.1 session. Also fix null-reference
when user PATH environment variable is empty.

* Fix executable resolution and tar extraction on Windows
resolveExecutable() used `sh -lc "command -v ..."` which doesn't work
on Windows (no sh). Now uses `cmd /c where` on win32. Also make tar
workspace restoration tolerate symlink failures on Windows — .bin/
symlinks can't be created without Developer Mode, but the actual
package directories are extracted fine.

* Broad Windows compatibility fixes across the codebase
- runtime.ts: Use path.delimiter instead of hardcoded ":" for PATH
construction — was completely broken on Windows
- executables.ts: Add Windows fallback paths for Chrome, Edge, Brave,
and Pandoc in Program Files; skip macOS-only paths on win32
- node-version.ts, check-node-version.mjs, bin/feynman.js: Show
Windows-appropriate install instructions (irm | iex, nodejs.org)
instead of nvm/curl on win32
- preview.ts: Support winget for pandoc auto-install on Windows, and
apt on Linux (was macOS/brew only)
- launch.ts: Catch unsupported signal errors on Windows
- README.md: Add Windows PowerShell commands alongside macOS/Linux
for all install instructions
