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 5: Agent Specs
+
+## STEP GOAL:
+
+Create agent placeholder/spec files based on the brief.
+
+## 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 Builder** — creating agent specs
+- ✅ These are specs, not full agents (agent-builder does that)
+- ✅ Keep it high-level
+
+---
+
+## MANDATORY SEQUENCE
+
+### 1. Load Agent Architecture
+
+Load `{agentArchitectureFile}` for guidance.
+
+### 2. Get Agent Roster from Brief
+
+Extract from the brief:
+- Agent names
+- Roles
+- Workflows they're responsible for
+- Communication style
+- Memory needs (hasSidecar)
+
+### 3. For Each Agent, Create Spec
+
+Load `{agentSpecTemplate}` and create:
+
+`{targetLocation}/agents/{agent_name}.spec.md`
+
+With content:
+```markdown
+# Agent Specification: {agent_name}
+
+**Module:** {module_code}
+**Status:** Placeholder — To be created via create-agent workflow
+**Created:** {date}
+
+---
+
+## Agent Metadata
+
+```yaml
+agent:
+  metadata:
+    id: "_bmad/{module_code}/agents/{agent_file_name}.md"
+    name: {agent_human_name}
+    title: {agent_title}
+    icon: {agent_icon}
+    module: {module_code}
+    hasSidecar: {false/true}
+```
+
+---
+
+## Agent Persona

+### Role

+### Identity

+{agent_identity}
+
+### Communication Style

+{agent_communication_style}
+
+### Principles

+{agent_principles}

+
+## Agent Menu
+
+### Planned Commands
+
+| Trigger | Command | Description | Workflow |
+|---------|---------|-------------|----------|
+{agent_menu_table}

+
+## Agent Integration
+
+### Shared Context
+
+- References: `{shared_context_files}`
+- Collaboration with: {collaborating_agents}
+
+### Workflow References

+
+## Implementation Notes
+
+**Use the create-agent workflow to build this agent.**
+
+---
+
+_Spec created on {date} via BMAD Module workflow_
+```
+
+### 4. Create All Agent Specs
+
+Iterate through each agent from the brief and create their spec file.
+
+### 5. Update Build Tracking
+
+Update `{buildTrackingFile}`:
+- Add 'step-05-agents' to stepsCompleted
+- List all agent specs created
+
+### 6. Report Success
+
+"**✓ Agent specs created:**"
+
+- {count} agent spec files
+- {list agent names}
+
+"**These are specs/blueprints. Use the create-agent workflow to build each agent.**"
+
+### 7. MENU OPTIONS
+
+**Select an Option:** [C] Continue
+
+- IF C: Update tracking, load `{nextStepFile}`
+- IF Any other: Help, then redisplay menu
+
+---
+
+## Success Metrics
+
+✅ Agent spec files created for all agents
+✅ Each spec has role, workflows, menu triggers
+✅ hasSidecar documented (memory decision)
+✅ Build tracking updated
