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 4: Module Installer
+
+## STEP GOAL:
+
+Setup the _module-installer folder and create installer.js if needed.
+
+## 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** — installer expert
+- ✅ Not all modules need installers
+- ✅ Follow installer patterns
+
+---
+
+## MANDATORY SEQUENCE
+
+### 1. Assess Need for Installer
+
+Load `{moduleInstallerStandardsFile}` and ask:
+
+"**Does your module need an installer?**"
+
+Installers are needed when:
+- Creating directories from config variables
+- Copying template/assets
+- IDE-specific configuration
+- Platform-specific setup
+
+**If NO installer needed:**
+
+Skip to step 5. Folder structure already exists.
+
+**If YES:** Continue to step 4.2
+
+### 2. Determine Installer Requirements
+
+"**What should the installer do?**"
+
+- Create directories? (which variables)
+- Copy assets? (from where)
+- IDE configuration? (which IDEs)
+- Platform-specific setup?
+
+### 3. Create installer.js
+
+Create `{targetLocation}/_module-installer/installer.js`:
+
+```javascript
+const fs = require('fs-extra');
+const path = require('node:path');
+const chalk = require('chalk');
+const platformCodes = require(path.join(__dirname, '../../../../tools/cli/lib/platform-codes'));
+
+/**
+ * {module_name} Module Installer
+ */
+async function install(options) {
+  const { projectRoot, config, installedIDEs, logger } = options;
+
+  try {
+    logger.log(chalk.blue('Installing {module_name}...'));
+
+    // Create directories
+    if (config['{variable_name}']) {
+      const dirConfig = config['{variable_name}'].replace('{project-root}/', '');
+      const dirPath = path.join(projectRoot, dirConfig);
+      if (!(await fs.pathExists(dirPath))) {
+        logger.log(chalk.yellow(`Creating directory: ${dirConfig}`));
+        await fs.ensureDir(dirPath);
+      }
+    }
+
+    // IDE-specific configuration
+    if (installedIDEs && installedIDEs.length > 0) {
+      for (const ide of installedIDEs) {
+        await configureForIDE(ide, projectRoot, config, logger);
+      }
+    }
+
+    logger.log(chalk.green('✓ {module_name} installation complete'));
+    return true;
+  } catch (error) {
+    logger.error(chalk.red(`Error installing module: ${error.message}`));
+    return false;
+  }
+}
+
+async function configureForIDE(ide, projectRoot, config, logger) {
+  if (!platformCodes.isValidPlatform(ide)) {
+    logger.warn(chalk.yellow(`Unknown platform: '${ide}'. Skipping.`));
+    return;
+  }
+
+  const platformSpecificPath = path.join(__dirname, 'platform-specifics', `${ide}.js`);
+
+  try {
+    if (await fs.pathExists(platformSpecificPath)) {
+      const platformHandler = require(platformSpecificPath);
+      if (typeof platformHandler.install === 'function') {
+        await platformHandler.install({ projectRoot, config, logger });
+      }
+    }
+  } catch (error) {
+    logger.warn(chalk.yellow(`Warning: Could not configure ${ide}: ${error.message}`));
+  }
+}
+
+module.exports = { install };
+```
+
+Customize based on module requirements.
+
+### 4. Platform-Specific Handlers (Optional)
+
+If IDE-specific setup needed, ask which IDEs and create:
+- `{targetLocation}/_module-installer/platform-specifics/claude-code.js`
+- `{targetLocation}/_module-installer/platform-specifics/windsurf.js`
+- etc.
+
+### 5. Update Build Tracking
+
+Update `{buildTrackingFile}`:
+- Add 'step-04-installer' to stepsCompleted
+- Note: installer created or skipped
+
+### 6. MENU OPTIONS
+
+**Select an Option:** [C] Continue
+
+- IF C: Update tracking, load `{nextStepFile}`
+- IF Any other: Help, then redisplay menu
+
+---
+
+## Success Metrics
+
+✅ Assessed installer need
+✅ installer.js created (if needed)
+✅ Platform handlers created (if needed)
+✅ Build tracking updated
