Title: `npm` not found during Claude Code / Codex install — fnm not activated in piped execution scope

Labels: bug, windows

## Problem

When running the bootstrap via `irm ... | iex`, the script fails at the Claude Code section with:

iex : The term 'npm' is not recognized as the name of a cmdlet, function, script file, or operable program.

## Root Cause

The Node section correctly calls `fnm env --use-on-cd | Out-String | Invoke-Expression` to activate fnm, but when the script is executed via `iex` (piped), the Claude Code and Codex sections run in a child scope where fnm activation does not persist. By the time the script reaches `npm install -g @anthropic-ai/claude-code`, `npm` is not on PATH.

## Steps to Reproduce

1. Run `irm https://raw.githubusercontent.com/AojdevStudio/dev-bootstrap/main/bootstrap.ps1 | iex` on a fresh Windows machine
2. Watch Node, Python, and Bun install successfully
3. Script fails at `== Claude Code ==` with `npm not recognized`

## Fix

Add an fnm re-activation guard before each `npm install` call in the Claude Code and Codex sections:

```powershell
if (Get-Command fnm -ErrorAction SilentlyContinue) {
  fnm env --use-on-cd | Out-String | Invoke-Expression
}

Apply immediately before:

• npm install -g @anthropic-ai/claude-code
• npm install -g @openai/codex

Workaround

Run these manually after the bootstrap fails:

fnm env --use-on-cd | Out-String | Invoke-Expression
npm install -g @anthropic-ai/claude-code
npm install -g @openai/codex

Environment

• Windows 11
• PowerShell 5.1
• fnm installed via winget
