Tiny user-preferences store — JSON file in DATA_DIR.

|
|
Keeps UI-selected choices (engine picks, translator provider, …) across
|
|
process restarts without reaching for a DB table. Environment variables
|
|
still win — users who set `OMNIVOICE_TTS_BACKEND=…` are opting into an
|
|
explicit override that the UI cannot silently undo.

→ env var if set, else prefs.json value, else default.
