refactor: type TranscriptionService._streamer property

[ysdede]

🎯 What: Replaced the any type on the _streamer property with StatefulStreamingTranscriber | null by importing the type from parakeet.js.
💡 Why: This directly addresses the code health issue to replace the loose any typing. It improves codebase readability and maintainability by explicitly declaring the expected type interface for the streaming transcriber instance, enabling IDE support and type-checking.
✅ Verification: Verified via TypeScript's type-checker tsc --noEmit which completed successfully and by running the application's full Vitest suite to ensure no runtime regressions were introduced.
✨ Result: Improved static analysis and stronger, explicit type safety for TranscriptionService.

Code Review

This pull request refactors the _streamer property in TranscriptionService to enhance type safety. The property's type is updated from any to the specific StatefulStreamingTranscriber | null, with the StatefulStreamingTranscriber type imported from parakeet.js. This change correctly removes a loose type, improving static analysis and code maintainability. The implementation is sound and addresses the intended refactoring.
