fix: bootstrap adds Step 0 environment pre-flight check

- Node.js, pnpm/npm, global bin PATH, hermes CLI checks with FIX instructions
- Agent must pass all checks before proceeding to install
- Install commands changed from npm to pnpm (with npm fallback)
- hermes PATH guidance moved from Step 1 to Step 0

 ## Scenario A: Fresh Install
 
+### Step 0 — Environment pre-flight check
+
+Run ALL checks below BEFORE installing anything. If any check fails, fix it first — do NOT skip ahead.
+
+\`\`\`bash
+# 1. Node.js
+node --version   # need v20+
+# FIX: install via nvm (https://github.com/nvm-sh/nvm) or your OS package manager
+
+# 2. Package manager — pnpm (preferred) or npm
+pnpm --version || npm --version
+# FIX for pnpm: corepack enable pnpm   (Node 20+)
+#   or: npm install -g pnpm
+# If pnpm is not an option, npm works too — adjust install commands below
+
+# 3. Global bin directory is in PATH
+# For pnpm:
+pnpm root -g 2>/dev/null && pnpm bin -g
+# For npm:
+npm prefix -g
+# The "bin" directory printed above MUST be in your PATH.
+# Test: echo $PATH | tr ':' '\\n' | grep -E "(pnpm|npm|node)"
+# FIX: add the bin directory to ~/.profile or ~/.bashrc:
+#   export PATH="$(pnpm bin -g):$PATH"   # pnpm
+#   export PATH="$(npm prefix -g)/bin:$PATH"  # npm
+
+# 4. (uwf-hermes only) hermes CLI
+which hermes
+# FIX: if hermes is in a virtualenv, add it to PATH:
+#   export PATH="$HOME/.hermes/hermes-agent/.venv/bin:$PATH"
+#   or create a symlink: ln -s ~/.hermes/hermes-agent/.venv/bin/hermes ~/.local/bin/hermes
+\`\`\`
+
+**All checks must pass before continuing.** If you had to modify PATH, verify the change persists by opening a new shell or sourcing your profile.
