Add today-view plugin with Tana, ICS, and Donetick data sources

Implements an e-ink daily dashboard plugin ("today") with four sections:
date/focus/success header, agenda timeline, chores checklist, and
due/overdue task lists.

Data sources:
- Focus & success text: Tana daily note (src/sources/tana.ts)
- Due/overdue tasks: Tana task search (src/sources/tana.ts)
- Agenda events: ICS calendar feeds (src/sources/ics.ts)
- Chores: Donetick API (src/sources/donetick.ts)

All sources fetch in parallel and fall back gracefully on error.
Tests use mock HTTP servers with synthetic data — no real services needed.

 ## Project Overview
 
-TRMNLc is a self-hosted server that serves rendered calendar displays to [TRMNL](https://usetrmnl.com/) e-ink devices. It fetches ICS calendar feeds, renders them as HTML using React SSR, screenshots the HTML with Puppeteer (Firefox), dithers the image with ImageMagick for e-ink display, and serves it via the TRMNL device API.
-
-The UI is in Dutch (e.g., "VRIJ" = free, "BEZET" = busy, "VOLGENDE" = next, "DAARNA" = after that).
+TRMNLc is a self-hosted server that serves rendered displays to [TRMNL](https://usetrmnl.com/) e-ink devices. It renders plugin UIs as HTML using React SSR, screenshots with Puppeteer (Firefox), dithers with ImageMagick for e-ink, and serves via the TRMNL device API.
 
 ## Running
 
 ```bash
-# Install dependencies
 bun install
 
 # Run the server (requires Firefox and ImageMagick in PATH)
 FIREFOX=/path/to/firefox CONFIG_FILE=config.json COLORMAP=./colormap.png bun run src/web.ts
+
+# Run tests
+bun test
 ```
 
-The server runs on port 2300 by default (`BUN_PORT` env var). No test suite exists.
+The server runs on port 2300 by default (`BUN_PORT` env var). See `config.sample.json` for the config format.
 
 ## Architecture
 
-The request flow for `/api/display`:
+### Plugin system
 
-1. **`src/web.ts`** — Bun HTTP server. Reads `CONFIG_FILE` JSON mapping device MAC addresses to ICS URLs + device model. Handles `/api/setup`, `/api/display` (returns rendered PNG), `/api/display/html` (returns raw HTML), and `/api/render/:id/:ignore` (serves cached PNGs).
+Each device is configured with a `plugin` name and `settings` object. The plugin registry (`src/plugins.ts`) maps names to factory functions that return a `Renderable`. The `Renderable` interface (`src/template.ts`) requires `hash`, `nextEvent?`, and `async render()`.
 
-2. **`src/xlcalendar.tsx`** — `ICSRenderable` class. Fetches ICS feeds via `node-ical`, expands recurring events, processes them into current/next/secondary slots, and renders a React component to HTML via `renderToString`. Computes a content hash and calculates the next refresh time based on upcoming events.
+Available plugins:
 
-3. **`src/template.ts`** — Wraps plugin HTML output in a full HTML page with TRMNL's CSS/JS framework. Defines the `Renderable` interface and `RenderMode` type (`full`, `half_horizontal`, `half_vertical`, `quadrant`).
+- **`calendar`** — Full-screen ICS calendar view with current/next/later event slots. UI is in Dutch ("VRIJ", "BEZET", "VOLGENDE"). Implementation: `src/xlcalendar.tsx`.
+- **`today`** — Daily dashboard with date header, focus/success lines, agenda timeline, chores checklist, and due/overdue tasks. Implementation: `src/todayview.tsx`.
 
-4. **`src/render.ts`** — Uses Puppeteer (Firefox) to screenshot the rendered HTML, then pipes through ImageMagick (`magick`) to dither to a 2-bit grayscale PNG using the colormap.
+### Data sources (`src/sources/`)
 
-5. **`src/devices.ts`** — Fetches device model definitions (screen dimensions, CSS classes) from `trmnl.com/api/models` at startup.
+The today plugin fetches from external services during `render()`, all in parallel:
+
+- **`tana.ts`** — Fetches daily focus/success text and due/overdue tasks from a Tana server. Focus: calendar node → markdown field parsing. Tasks: single search query (`lt` tomorrow), split client-side by due date.
+- **`ics.ts`** — Fetches today's non-full-day events from ICS feeds, returns `AgendaEvent[]`. Note: `location` lives on `instance.event.location`, not on the expanded instance directly.
+- **`donetick.ts`** — Fetches chores from a Donetick instance (defaults to `app.donetick.com`). Filters by `user_id` and `isActive`. Done status: `nextDueDate > today` means completed.
+
+### Config structure
+
+```json
+{
+  "base_url": "http://host:2300",
+  "devices": {
+    "DEVICE_MAC": {
+      "plugin": "today",
+      "settings": { ... },
+      "refresh": 300,
+      "model": "inkplate_10"
+    }
+  }
+}
+```
+
+### Render pipeline
+
+1. **`src/web.ts`** — Bun HTTP server. Routes: `/api/setup`, `/api/display` (PNG), `/api/display/html` (raw HTML), `/api/render/:id/:ignore` (cached PNGs).
+2. **`src/template.ts`** — Wraps plugin HTML in a full page with TRMNL's CSS/JS framework.
+3. **`src/render.ts`** — Puppeteer (Firefox) screenshots the HTML, then ImageMagick dithers to 2-bit grayscale PNG.
+4. **`src/devices.ts`** — Fetches device model definitions (screen dimensions, CSS classes) from `trmnl.com/api/models` at startup.
