Replaces the original overview with a comprehensive execution plan for Owlen v0.2, including:
- Provider health checks and resilient model listing for Ollama and Ollama Cloud
- Cloud key‑gating, rate‑limit handling, and usage tracking
- Multi‑provider model registry and UI aggregation
- Session pipeline refactor for tool calls and partial updates
- Robust streaming JSON parser
- UI header displaying context usage percentages
- Token usage tracker with hourly/weekly limits and toasts
- New web.search tool wrapper and related commands
- Expanded command set (`:provider`, `:model`, `:limits`, `:web`) and config sections
- Additional documentation, testing guidelines, and release notes for v0.2.
- 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.
Update pkgver in PKGBUILD, version badge in README, and workspace package version in Cargo.toml. Add changelog entry for 0.1.11 reflecting the metadata bump.
- New test suite in `crates/owlen-tui/tests` covering generation orchestration, message variant round‑trip, and background worker status updates.

- 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.
Introduce `App` with provider manager, unbounded message channel, and active generation tracking.
Add `AppMessage` enum covering UI events, generation lifecycle (start, chunk, complete, error), model refresh, and provider status updates.
Implement `start_generation` to spawn asynchronous generation tasks, stream results, handle errors, and abort any previous generation.
Expose the new module via `pub mod app` in the crate root.
Introduce `OllamaCloudProvider` that resolves the API key from configuration or the `OLLAMA_CLOUD_API_KEY` environment variable, constructs provider metadata (including timeout as numeric), and maps auth errors to `ProviderStatus::RequiresSetup`. Export the new provider in the `ollama` module. Add shared HTTP error mapping utilities (`map_http_error`, `truncated_body`) and update local provider metadata to store timeout as a number.
Introduce `OllamaLocalProvider` for communicating with a local Ollama daemon, including health checks, model listing, and stream generation. Export the provider in the Ollama module. Extend `OllamaClient` to accept an optional request timeout and apply it to the underlying HTTP client configuration.

- Expose `OllamaClient` handling HTTP communication, health checks, model listing, and streaming generation.
- Implement request building, endpoint handling, and error mapping.
- Parse Ollama tags response and generation stream lines into core types.
- Add shared module re-exports for easy integration with the provider layer.
- Introduce `ProviderManager` for registering providers, routing generate calls, listing models, and refreshing health in parallel.
- Maintain a status cache to expose the last known health of each provider.
- Update `provider` module to re‑export the new manager alongside existing types.
- Introduce `MIN_MESSAGE_CARD_WIDTH` and use it to switch to compact card layout when terminal width is limited.
- Implement `clip_line_to_width` to truncate UI lines based on available width, preventing overflow in model selector and headers.
- Adjust viewport and card width calculations to respect inner area constraints and handle compact cards.
- Update resize handling and rendering logic to use the new width calculations and clipping functionality.
- Rename “PANEL NAVIGATION” to “PANEL FOCUS” and document Ctrl/Alt + 1‑5 panel focus shortcuts.

- Include “TIPS” section highlighting slash commands and focus behavior.
- Implement `focus_panel` to programmatically switch between panels with validation.
- Add key bindings for `Ctrl+1`‑`Ctrl+5` to focus Files, Chat, Code, Thinking, and Input panels respectively.
- Update pane headers to display focus shortcuts alongside panel labels.
- Extend UI hint strings across panels to include the new focus shortcuts.
- Refactor highlight style handling and introduce a dedicated `highlight_style`.
- Adjust default theme colors to use explicit RGB values for better consistency.
Implemented full markdown table support:
- Parse tables with headers, rows, and alignment.
- Render tables as a grid when width permits, falling back to a stacked layout for narrow widths.

- Integrated table rendering into `render_markdown_lines`.
- Added unit tests for grid rendering and narrow fallback behavior.
- Introduce new `owlen-markdown` crate that converts Markdown strings to `ratatui::Text` with headings, lists, bold/italic, and inline code.

- Implement `:markdown [on|off]` command to toggle markdown rendering.
- Update help overlay to document the new markdown toggle.
- Adjust UI rendering to conditionally apply markdown styling based on the markdown flag and code mode.
- Wire the new crate into `owlen-tui` Cargo.toml.
- Set `default_syntax_highlighting` to true in core config.
- Added language‑aware syntax selector (`select_syntax_for_language`) and highlighter builder (`build_highlighter_for_language`) with unit test.
- Integrated new highlight module into `ChatApp`, using `UnicodeSegmentation` for proper grapheme handling.
- Simplified `should_highlight_code` to always return true and removed extended‑color detection logic.
- Reworked code rendering to use `inline_code_spans_from_text` and `wrap_highlight_segments` for accurate line wrapping and styling.

- Introduce `populate_model_details_cache_from_session` to load model details from the controller, with a fallback to cached details.
- Update `refresh_models` to use the new cache‑population method instead of manually clearing the cache.
- Add robust size calculations with configurable width bounds and height clamping.
- Guard against zero‑size areas and empty model/theme lists.
- Render popups centered with dynamic positioning, preventing negative Y coordinates.
- Introduce multi‑line list items, badges, and metadata display for models.
- Add ellipsis helper for long descriptions and separate title/metadata generation.
