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 6: Documentation Validation
+
+## STEP GOAL:
+
+Validate module documentation completeness, including user-facing docs in docs/ folder.
+
+## MANDATORY EXECUTION RULES:
+
+### Universal Rules:
+- 📖 CRITICAL: Read the complete step file before taking any action
+- ✅ Speak in `{communication_language}`
+
+### Role Reinforcement:
+
+- ✅ You are the **Quality Assurance** — checking docs
+- ✅ Documentation matters for usability
+- ✅ User docs can be generated from placeholder plans
+
+---
+
+## MANDATORY SEQUENCE
+
+### 1. Load Documentation Files
+
+Check for:
+- `{targetPath}/README.md` (module overview)
+- `{targetPath}/TODO.md` (development roadmap)
+- `{targetPath}/docs/` (user documentation folder)
+
+### 2. Validate README.md
+
+**Required Sections:**
+- [ ] Module name and description
+- [ ] Installation instructions
+- [ ] Components section (agents, workflows)
+- [ ] Usage examples or quick start
+- [ ] Module structure
+- [ ] Link to docs/ folder
+
+**Quality Checks:**
+- [ ] Clear description of what module does
+- [ ] Installation command shown
+- [ ] Agent/workflow lists complete
+- [ ] References user documentation
+
+### 3. Validate TODO.md
+
+**Required Content:**
+- [ ] Agent build checklist
+- [ ] Workflow build checklist
+- [ ] Testing section
+- [ ] Next steps
+
+### 4. Validate docs/ Folder
+
+**For Custom Modules:**
+- [ ] docs/ folder exists
+- [ ] Contains user-facing documentation
+- [ ] Documentation is clear and helpful
+
+**Valid docs/ Contents (may include):**
+- `getting-started.md` — Quick start guide
+- `agents.md` — Agent documentation
+- `workflows.md` — Workflow documentation
+- `examples.md` — Usage examples
+- `configuration.md` — Setup/configuration guide
+- `troubleshooting.md` — Common issues and solutions
+
+**Quality Check:**
+- [ ] Even with placeholder agent/workflow specs, user docs should provide useful information
+- [ ] Documentation references agents/workflows by name
+- [ ] Clear what functionality exists vs what is planned
+
+### 5. Generate User Docs Recommendation
+
+**IF docs/ missing or incomplete:**
+
+"**User documentation can be generated from module brief and agent/workflow specs.**"
+
+"**Even with placeholder plans, you can create helpful user documentation that describes:**
+- What each agent does and when to use it
+- What workflows are available and their purpose
+- How to get started with the module
+- Configuration options (from module.yaml)"
+
+### 6. Record Results
+
+Append to `{validationReportOutput}`:
+
+```markdown
+## Documentation Validation
+
+**Status:** {PASS/FAIL/WARNINGS}
+
+**Root Documentation:**
+- **README.md:** {present/missing} - {status}
+- **TODO.md:** {present/missing} - {status}
+
+**User Documentation (docs/):**
+- **docs/ folder:** {present/missing} - {status}
+- **Documentation files:** {count} files found
+
+**Docs Contents:**
+{list files in docs/ folder}
+
+**Issues Found:**
+{list any issues}
+
+**Recommendations:**
+{if docs/ missing or incomplete}
+- Generate user documentation from module brief and specs
+- Create getting-started.md, agents.md, workflows.md
+- User docs are valuable even with placeholder plans
+{endif}
+```
+
+### 7. Auto-Proceed
+
+"**✓ Documentation check complete.**"
+
+Proceeding to installation validation...
+
+Load `{nextStepFile}`
+
+---
+
+## Success Metrics
+
+✅ All documentation checked
+✅ Required sections validated
+✅ docs/ folder presence verified
+✅ User documentation quality assessed
+✅ Recommendations documented
