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

+# Validate Step 2a: Validate Metadata
+
+## STEP GOAL
+
+Validate the agent's metadata properties against BMAD standards as defined in agentMetadata.md. Append findings to validation report and auto-advance.
+
+## MANDATORY EXECUTION RULES
+
+- 📖 CRITICAL: Read the complete step file before taking any action
+- 🔄 CRITICAL: Read validationReport and agentMetadata first
+- 🔄 CRITICAL: Load the actual agent file to validate metadata
+- 🚫 NO MENU - append findings and auto-advance
+- ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the config `{communication_language}`
+
+### Step-Specific Rules:
+
+- 🎯 Validate metadata against agentMetadata.md rules
+- 📊 Append findings to validation report
+- 🚫 FORBIDDEN to present menu
+
+## EXECUTION PROTOCOLS
+
+- 🎯 Load agentMetadata.md reference
+- 🎯 Load the actual agent file for validation
+- 📊 Validate all metadata fields
+- 💾 Append findings to validation report
+- ➡️ 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 References
+
+Read `{agentMetadata}`, `{validationReport}`, and `{agentFile}`.
+
+### 2. Validate Metadata
+
+Perform these checks systematically - validate EVERY rule specified in agentMetadata.md:
+
+1. **Required Fields Existence**
+   - [ ] id: Present and non-empty
+   - [ ] name: Present and non-empty (display name)
+   - [ ] title: Present and non-empty
+   - [ ] icon: Present (emoji or symbol)
+   - [ ] module: Present and valid format
+   - [ ] hasSidecar: Present (boolean, if applicable)
+
+2. **Format Validation**
+   - [ ] id: Uses kebab-case, no spaces, unique identifier
+   - [ ] name: Clear display name for UI
+   - [ ] title: Concise functional description
+   - [ ] icon: Appropriate emoji or unicode symbol
+   - [ ] module: Either a 3-4 letter module code OR 'stand-alone'
+   - [ ] hasSidecar: Boolean value, matches actual agent structure
+
+3. **Content Quality**
+   - [ ] id: Unique and descriptive
+   - [ ] name: Clear and user-friendly
+   - [ ] title: Accurately describes agent's function
+   - [ ] icon: Visually representative of agent's purpose
+   - [ ] module: Correctly identifies module membership
+   - [ ] hasSidecar: Correctly indicates if agent uses sidecar files
+
+4. **Agent Type Consistency**
+   - [ ] If hasSidecar: true, sidecar folder path must be specified
+   - [ ] If module is a module code, agent is a module agent
+   - [ ] If module is 'stand-alone', agent is not part of a module
+   - [ ] No conflicting type indicators
+
+### 3. Append Findings to Report
+
+Append to `{validationReport}`:
+
+```markdown
+### Metadata Validation
+
+**Status:** {✅ PASS / ⚠️ WARNING / ❌ FAIL}
+
+**Checks:**
+- [ ] id: kebab-case, no spaces, unique
+- [ ] name: clear display name
+- [ ] title: concise function description
+- [ ] icon: appropriate emoji/symbol
+- [ ] module: correct format (code or stand-alone)
+- [ ] hasSidecar: matches actual usage
+
+**Detailed Findings:**
+
+*PASSING:*
+{List of passing checks}
+
+*WARNINGS:*
+{List of non-blocking issues}
+
+*FAILURES:*
+{List of blocking issues that must be fixed}
+```
+
+### 4. Auto-Advance
+
+Load and execute `{nextStepFile}` immediately.
