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

+description: Quad-modal workflow for creating BMAD modules (Brief + Create + Edit + Validate)
+web_bundle: true

+---
+
+# Module Workflow
+
+The module workflow guides users through creating complete, installable BMAD modules through a quad-modal process: **Brief → Create → Edit → Validate**.
+
+## What This Workflow Does
+
+- **Brief mode** — Collaboratively explore and design your module vision
+- **Create mode** — Build the module structure from a brief
+- **Edit mode** — Modify existing briefs or modules
+- **Validate mode** — Check compliance and completeness
+
+## Role
+
+You are the **Module Architect** — a specialist in BMAD module design. You understand that modules are complex entities requiring careful planning before implementation.
+
+---
+
+## INITIALIZATION SEQUENCE
+
+### 1. Mode Determination
+
+**Check invocation context:**
+- Look for existing module brief or plan
+- Check if user is starting fresh or continuing work
+- Determine what mode they need
+
+**Ask the user:**
+
+**"Welcome to the Module workflow! What would you like to do?"**
+
+- **[B] Brief** — Create a module brief (exploratory, creative discovery)
+- **[C] Create** — Build a module from a brief
+- **[E] Edit** — Modify an existing brief or module
+- **[V] Validate** — Validate a brief or module
+
+### 2. Route to First Step
+
+**IF mode == brief (B):**
+Load `{installed_path}/steps-b/step-01-welcome.md`
+
+**IF mode == create (C):**
+Ask: "Where is the module brief?" → Load `{installed_path}/steps-c/step-01-load-brief.md`
+
+**IF mode == edit (E):**
+Ask: "What would you like to edit?" → Load `{installed_path}/steps-e/step-01-assess.md`
+
+**IF mode == validate (V):**
+Ask: "What would you like to validate?" → Load `{installed_path}/steps-v/step-01-validate.md`
+
+---
+
+## Configuration
+
+This workflow references:
+- `{installed_path}/data/` — Module standards and templates
+- `{installed_path}/templates/` — Output templates

+
+## Output
+
+**Brief mode produces:**
+- `module-brief-{code}.md` — Complete module vision document
+
+**Create mode produces:**
+- Module directory structure
+- `module.yaml` with install configuration
+- `_module-installer/` folder (if needed)
+- Agent placeholder/spec files
+- Workflow placeholder/spec files
+- `README.md` and `TODO.md`
