//  RuntimeAssets — readiness of the runtime data payload next to the exe
//
//  Kokoro TTS (voices/, kokoro.onnx) and the SearchPioneer.Lingua language
//  models (Lingua/LanguageModels/) are DISTRIBUTION CONTENT: they ship inside
//  the release archive (see the CopyTtsAssetsToPublish / CopyLinguaModels*
//  csproj targets) and are read from the app base directory at runtime.
//  A freshly installed app therefore always has them. An OLD installation
//  that predates a payload (e.g. Lingua was never shipped before 2026-09)
//  runs with the assets missing until its next auto-update: nothing must
//  crash or show a technical error in that window — the app stays fully
//  functional and surfaces a clear, human "setup incomplete" state instead.
//  This class is the single check consumed by /v1/control capabilities,
//  the TUI status and the startup console note.
