fix: resolve VS Code settings type error and markdown duplicate heading

VS Code Settings Fix (.vscode/settings.json line 84):
- Changed terminal.integrated.suggest.quickSuggestions from boolean to object
- Proper configuration: {other: true, comments: false, strings: true}
- Fixes JSON schema validation error (expected object, got boolean)

Markdownlint Fix (.devcontainer/README.md line 425):
- MD024: Renamed h3 'Troubleshooting' to 'Shell Integration Troubleshooting'
- Avoids duplicate heading conflict with h2 'Troubleshooting' at line 205
- Maintains clear section organization for shell integration issues

PowerShell Syntax (test-docker-stack.ps1):
- Verified with PSParser: Syntax is valid, no errors
- Line 202 try-catch structure is correct
- VS Code diagnostic is a false positive (all try blocks have catch blocks)

Note: terminal.integrated.suggest.quickSuggestions object format enables
granular control over IntelliSense suggestions in different contexts.
