fix: prevent model auto-switch from interrupting active transcription (cjpais#443)

* fix: prevent model auto-switch from interrupting active transcription

when a model download completes during an active recording/transcription,
the app now skips auto-switching to prevent data loss.

adds is_recording tauri command to check recording state before
auto-switching models on download or extraction completion.

fixes cjpais#418

* Update bindings.ts
