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

+# Edit Step 8b: Edit Expert Agent
+
+## STEP GOAL:
+
+Apply all planned edits to the Expert agent YAML file and manage sidecar structure changes.
+
+## MANDATORY EXECUTION RULES:
+
+- 🛑 ALWAYS create backup before modifying agent file
+- 📖 CRITICAL: Read template and architecture files first
+- 🔄 CRITICAL: Load editPlan and agentFile
+- ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the config `{communication_language}`
+
+### Step-Specific Rules:
+
+- 🎯 Load all reference files before applying edits
+- 📊 Manage sidecar structure for Expert agents
+- 💾 Validate YAML and sidecar paths after edits
+- ➡️ Auto-advance to post-edit validation when complete
+
+## EXECUTION PROTOCOLS:
+
+- 🎯 Load template, architecture, and data files
+- 📊 Read editPlan to get all planned changes
+- 💾 Create backup
+- 📝 Apply edits including sidecar management
+- ✅ Validate YAML and sidecar paths
+- ➡️ Auto-advance to next validation step
+
+## MANDATORY SEQUENCE
+
+**CRITICAL:** Follow this sequence exactly. Do not skip, reorder, or improvise unless user explicitly requests a change.
+
+### 1. Load Reference Documents
+
+Read all files before editing:
+- `{expertTemplate}` - Expert YAML structure
+- `{expertArch}` - Expert agent architecture
+- `{agentCompilation}`, `{agentMetadata}`, `{personaProperties}`, `{principlesCrafting}`
+- `{agentMenuPatterns}`, `{criticalActions}`, `{expertValidation}`
+
+### 2. Load Edit Plan and Agent
+
+Read `{editPlan}` to get all planned edits.
+Read `{agentFile}` to get current agent YAML.
+
+### 3. Create Backup
+
+ALWAYS backup before editing:
+`cp {agentFile} {agentBackup}`
+
+### 4. Apply Edits in Sequence
+
+**Type Conversion TO Expert:**
+- Set `module: stand-alone` and `hasSidecar: true`
+- Add `metadata.sidecar-folder` if not present
+- Create sidecar directory next to agent.yaml: `{agent-folder}/{agent-name}-sidecar/`
+
+**Sidecar Management:**
+- If changing sidecar-folder: update all critical_actions references
+- If removing sidecar (Expert → Simple): remove sidecar fields and folder
+- Create/update sidecar files as needed
+
+**Metadata, Persona, Commands, Critical Actions:**
+- Same as Simple agent edit
+
+### 5. Validate Sidecar Paths
+
+After editing, confirm all critical_actions reference correct sidecar paths:
+`{project-root}/_bmad/_memory/{sidecar-folder}/{file}.md`
+
+### 6. Document Applied Edits
+
+Append to `{editPlan}` with sidecar changes noted.
+
+### 7. Auto-Advance
+
+When all edits applied successfully, load and execute `{nextStepFile}` immediately.
+
+## SUCCESS METRICS
+
+✅ Backup created
+✅ All reference files loaded
+✅ All edits applied correctly
+✅ YAML remains valid
+✅ Sidecar structure correct
+✅ Sidecar paths validated
+
+## FAILURE MODES
+
+❌ Backup failed
+❌ YAML became invalid
+❌ Sidecar paths broken
+❌ Edits not applied as specified
