refactor(details): use sealed interface for TranslationTarget and improve translation handling

This commit refines the translation logic and search behavior while fixing some minor issues in URL parsing and clipboard detection. Key changes include converting the `TranslationTarget` to a sealed interface for better type safety and improving how translated text chunks are joined to preserve delimiters.

- **refactor(details)**: Converted `TranslationTarget` from an `enum` to a `sealed interface`.
- **refactor(details)**: Updated `TranslationRepositoryImpl` to correctly preserve delimiters between translated text chunks and added a fallback for parsing failures.
- **fix(search)**: Hardened `GITHUB_URL_REGEX` with a negative lookbehind to prevent incorrect matches on prefixed strings.
- **fix(search)**: Updated `SearchViewModel` to clear repository results and reset loading states when the query is cleared or multiple links are detected in the clipboard.
- **fix(core)**: Changed the default value of `AUTO_DETECT_CLIPBOARD_KEY` from `true` to `false` in `ThemesRepositoryImpl`.
- **chore**: Updated `DetailsRoot` to reflect `TranslationTarget` naming changes (`About`/`WhatsNew`).
