Test Notes:\n- cargo check
Acceptance Criteria:\n- header shows hourly/weekly usage with colored thresholds\n- :limits command prints persisted usage data and quotas\n- token usage survives restarts and emits 80%/95% toasts
Test Notes:\n- cargo test -p owlen-core usage
Acceptance Criteria:\n- tool descriptors from MCP are forwarded to Ollama chat requests\n- models advertise tool support when metadata or heuristics imply function calling\n- chat responses include provider metadata with final token metrics

Test Notes:\n- cargo test -p owlen-providers
- Introduce `StreamingMessageState` to track full text, last tool calls, and completion.
- Add `StreamDiff`, `TextDelta`, and `TextDeltaKind` for describing incremental changes.
- SessionController now maintains a `stream_states` map keyed by response IDs.
- `apply_stream_chunk` uses the new state to emit append/replace text deltas and tool‑call updates, handling final chunks and cleanup.
- `Conversation` gains `set_stream_content` to replace streaming content and manage metadata.
- Ensure stream state is cleared on cancel, conversation reset, and controller clear.
- Introduce built‑in Emacs keymap (`keymap_emacs.toml`) alongside existing Vim layout.
- Add `ui.keymap_profile` and `ui.keymap_path` configuration options; persist profile changes via `:keymap` command.
- Expose `KeymapProfile` enum (Vim, Emacs, Custom) and integrate it throughout state, UI rendering, and help overlay.
- Extend command registry with `keymap.set_vim` and `keymap.set_emacs` to allow profile switching.
- Update help overlay, command specs, and README to reflect new keybindings and profile commands.
- Adjust `Keymap::load` to honor preferred profile, custom paths, and fallback logic.
- Extend event handling to include `MouseEvent` and expose it via a new `Event::Mouse` variant.
- Introduce `LayoutSnapshot` to capture the geometry of UI panels each render cycle.
- Store the latest layout snapshot in `ChatApp` for mouse region lookup.
- Implement mouse click and scroll handling across panels (file tree, thinking, actions, code, model info, chat, input, etc.).
- Add utility functions for region detection, cursor placement from mouse position, and scrolling logic.
- Update UI rendering to populate the layout snapshot with panel rectangles.
- New test suite in `crates/owlen-tui/tests` covering generation orchestration, message variant round‑trip, and background worker status updates.
- Extend `model_picker` to filter models by matching keywords against capabilities as well as provider names.
- Update `state_tests` to assert that suggestion lists are non‑empty instead of checking prefix matches.
- Re‑export `background_worker` from `app::mod.rs` for external consumption.
- Introduce `MockProvider` with configurable models, health status, generation handlers, and error simulation.
- Add common test utilities and integration tests covering provider registration, model aggregation, request routing, error handling, and health refresh.
- Add `MessageState` trait defining UI reaction callbacks for generation lifecycle, model updates, provider status, resize, and tick events.
- Implement `App::handle_message` to route `AppMessage` variants to the provided `MessageState` and determine exit condition.
- Add `handler.rs` module with the trait and dispatch logic; re-export `MessageState` in `app/mod.rs`.
- Extend `ActiveGeneration` with a public `request_id` getter and clean up dead code annotations.
- Implement empty `MessageState` for `ChatApp` to integrate UI handling.
- Add `log` crate dependency for warning messages.
Added `widgets::model_picker` containing the full model picker rendering logic and moved related helper functions there. Updated `ui.rs` to use `render_model_picker` and removed the now‑duplicate model selector implementation. This cleanly separates UI concerns and improves code reuse.
Introduce a `worker` module with `background_worker` that periodically refreshes provider health and emits status updates via the app's message channel. Add `spawn_background_worker` method to `App` for launching the worker as a Tokio task.
