Surfaces the LLM/TTS hot-swap UX in the GUI so the user doesn't need env vars
or voice commands. Tauri commands for this landed in b243e67; this commit
wires them to Svelte.
Footer (frontend/src/components/Footer.svelte)
- Poll get_active_backends() every 5 s, show TTS / LLM / Profile chips.
- Chips have border accents by kind (cyan = TTS, lime = LLM, orange = Profile).
- Friendly title tooltips with full backend + model names.
- Silent if jarvis-gui can't reach the command (e.g. cold start) — no UI flicker.
Settings — new "AI Backends" tab (frontend/src/routes/settings/index.svelte)
- Status banner showing active LLM (with model name) + TTS + Profile.
- LLM selector: Auto / Groq / Ollama → calls set_llm_backend on change
(hot-swap, persisted to DB).
- TTS selector: Auto / SAPI / Piper / Silero → calls set_tts_backend
(persisted, effective on next jarvis-app restart).
- "Reset context" button → llm_reset_context Tauri command.
- Error toast for swap failures (e.g. Groq selected but no GROQ_TOKEN).
- Tips alert: how to install Ollama / Piper / voice commands.
- Loads prefs via db_read('llm_backend' / 'tts_backend') on mount.
i18n strings (ru/en/ua, .ftl files)
- 14 new keys: settings-ai-backends, settings-ai-active, settings-ai-auto,
settings-ai-applying, settings-ai-error, settings-ai-tips,
settings-llm-backend{,-desc}, settings-tts-backend{,-desc},
settings-llm-context{,-desc}, settings-llm-reset, settings-profile.
Build glue (crates/jarvis-gui/Cargo.toml)
- jarvis-core dep now includes the `llm` feature so backends.rs can resolve
`jarvis_core::llm::*` (was failing to compile after the global LLM module).
.gitignore
- tools/piper/*.dll, piper.exe, voices/, espeak-ng-data/ — locally
installed binaries from tools/piper/install.ps1, not committed.
Build: cargo build --release -p jarvis-gui green (4m, includes npm/Vite).
Test path: rebuild + launch jarvis-gui, /settings → "AI Backends" tab.
