refactor: archive GUI clients; keep minimal TUI with hooks/API
Move Qt/Tauri/full Web SPA under archive/, ship hermit as CLI/TUI plus

// Provider, model and key: what the engine needs before it can talk to a model
// at all. Everything here goes through AgentCore, which moves the engine's own
// config (its session stays where it is) and remembers the choice. A key is
// verified against the provider before it is saved and is never read back into
// this window -- the dialog only ever says where the key it will use comes
// from.
//
// Three things live under "Advanced options", because they are for the odd
// provider or the odd model: the provider's own entry (name, base URL, key
// variable, models -- the engine keeps those in <config>/models.json, which is
// how a provider the presets do not know is added or an existing one is
// pointed somewhere else) and the generation parameters (temperature, top-p,
// max tokens), which are remembered per provider.
