Fix GLM chicken-and-egg problem in Master Prompt workflow

BREAKING CHANGES to workflow:
- Add 'BEFORE YOU BEGIN' section to MASTER-PROMPT.md
- GLM users MUST configure GLM FIRST before using Claude Code
- Add clear GLM pre-configuration steps at top of file
- Add clear copy boundaries (✂️ COPY FROM HERE / ✂️ COPY ENDS HERE)
- Add visual separator lines for copy-paste section

README.md updates:
- Add prominent GLM warning at top of Installation Options
- Add quick GLM setup commands
- Clarify Master Prompt workflow with step-by-step
- Emphasize GLM pre-configuration requirement

This fixes the issue where GLM users couldn't use Claude Code
to paste the master prompt without first configuring GLM.

+### ⚠️ IMPORTANT: For Z.AI / GLM Users
+
+**If using the GLM Coding Plan (90% cheaper), you MUST configure GLM FIRST before using Claude Code!**
+
+The Master Prompt file includes complete GLM setup instructions at the top. Read the "BEFORE YOU BEGIN" section first.
+
+**Quick GLM Setup:**
+```bash
+# Get API key: https://z.ai/
+mkdir -p ~/.claude
+cat > ~/.claude/settings.json << 'EOF'
+{
+  "env": {
+    "ANTHROPIC_AUTH_TOKEN": "YOUR_ZAI_API_KEY_HERE",
+    "ANTHROPIC_BASE_URL": "https://api.z.ai/api/anthropic",
+    "API_TIMEOUT_MS": "3000000",
+    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "glm-4.5-air",
+    "ANTHROPIC_DEFAULT_SONNET_MODEL": "glm-4.7",
+    "ANTHROPIC_DEFAULT_OPUS_MODEL": "glm-4.7"
+  }
+}
