refactor: Standardize method names and introduce context propagation

Removes the `Get` prefix from exporter methods (e.g., GetSupportedFormat -> SupportedFormat) to better align with Go conventions for simple accessors.

Introduces `context.Context` propagation through the application, starting from `ProcessCourseFromURI` down to the HTTP request in the parser. This makes network operations cancellable and allows for setting deadlines, improving application robustness.

Additionally, optimizes the HTML cleaner by pre-compiling regular expressions for a minor performance gain.
