🐛 fix(windows): remove broken fnm use --lts + catch silent npm failures

Observed on a fresh Windows 11 install test:

- `fnm use --lts` fails on recent fnm builds from winget with "unexpected
  argument '--lts' found". Because PowerShell does not halt on native
  command non-zero exit codes under $ErrorActionPreference = "Stop", the
  script continued past the error. `fnm install --lts` already activates
  the version in the current shell's multishell junction, so the follow-up
  call was both redundant and broken. Removed.

- `npm install -g @anthropic-ai/claude-code` produced no visible output and
  `Need claude` threw with a confusing "Missing command: claude" message.
  Two fixes:
  1. Re-activate fnm (`fnm env --use-on-cd --shell powershell | iex`)
     immediately before each `npm install -g` call so the multishell
     junction is guaranteed to be on PATH even after earlier winget calls.
  2. Check $LASTEXITCODE after the npm install and throw a clear error
     when it's non-zero, so silent failures surface immediately instead
     of cascading to a misleading "Missing command" message one section
     later.

+- Windows: removed `fnm use --lts` call that several recent fnm builds from winget reject with `unexpected argument '--lts' found`. `fnm install --lts` already activates the version in the current shell, so the follow-up call was both redundant and broken.
+- Windows: Claude Code and Codex install sections now re-activate fnm before calling `npm install -g`, then check `$LASTEXITCODE` and throw a clear error when npm fails. Prevents silent failures where the script continued and halted later with a confusing "Missing command: claude" message.
