Add Support for vendor extensions processing and related functions

- Implemented comprehensive tests for vendor extensions in the transform package, covering various scenarios including disabled extensions, valid OpenAPI files with pagination, and provider matching.
- Added utility functions for YAML parsing, template context building, and extension management.
- Enhanced test coverage for operations, parameter extraction, and response validation.
- Minor import adjustment in the TUI package to include the transform package.
