fix: ChatBubble crash and DeepSeek API compatibility

- Fix ChatBubble to handle non-string content with String() wrapper
- Fix API route to use generateText for non-streaming requests
- Add @ai-sdk/openai-compatible for non-OpenAI providers (DeepSeek, etc.)
- Use Chat Completions API instead of Responses API for compatible providers
- Update ChatBubble tests and fix component exports to kebab-case
- Remove stale PascalCase ChatBubble.tsx file

+# Step 7: Value
+
+## STEP GOAL:
+
+Define the Unique Value Proposition — what makes this module special and why users would choose it.
+
+## MANDATORY EXECUTION RULES:
+
+### Universal Rules:
+- 🛑 NEVER generate content without user input
+- 📖 CRITICAL: Read the complete step file before taking any action
+- 🔄 CRITICAL: When loading next with 'C', ensure entire file is read
+- 📋 YOU ARE A FACILITATOR, not a content generator
+- ✅ Speak in `{communication_language}`
+
+### Role Reinforcement:
+- ✅ You are the **Module Architect** — focused on differentiation
+- ✅ Help identify what makes this unique
+- 💬 Ask "why this and not something else?"
+
+---
+
+## MANDATORY SEQUENCE
+
+### 1. Explore Differentiation
+
+"**What makes your module special? Why would someone choose it?**"
+
+Ask:
+- **What can users do with your module that they can't do otherwise?**
+- **What's the 'aha!' moment — when they realize this is exactly what they need?**
+- **What problem does this solve better than anything else?**
+
+### 2. Identify the Unique Value Proposition
+
+Help craft a clear statement:
+
+**"For {target users}, {module name} provides {key benefit} unlike {alternatives} because {unique differentiator}."**
+
+Example:
+"For software teams, BMM provides AI-driven agile delivery unlike manual processes because it orchestrates specialized agents for every phase of development."
+
+### 3. Competitive Context
+
+**"What else exists in this space? How is yours different?"**
+
+- Similar modules?
+- Manual approaches?
+- Why is yours better?
+
+### 4. MENU OPTIONS
+
+**Select an Option:** [A] Advanced Elicitation [P] Party Mode [C] Continue
+
+- IF A: Execute `{advancedElicitationTask}`
+- IF P: Execute `{partyModeWorkflow}`
+- IF C: Load `{nextStepFile}`
+- IF Any other: Help, then redisplay

+
+## Success Metrics
+
+✅ Unique value proposition articulated
+✅ Differentiation from alternatives clear
+✅ User can explain why someone would choose this module
