fix: update hardcoded version references to use dynamic version

- Update DEFAULT_VERSION in version.ts from 3.5.1 to 3.14.0
- Replace hardcoded version in sharedConfigManager with getBrainyVersion()
- Replace hardcoded CLI version display with dynamic version
- Ensures all user-facing version displays stay current automatically
