Restructure repository: organize blueprints into folders

Each blueprint now has its own folder containing:
- blueprint.yaml: The automation code with a short header
- README.md: Detailed documentation extracted from headers

Updated CLAUDE.md with repository structure guidelines.

+# Washing Machine / Dryer Notifications Blueprint
+
+This blueprint monitors washing machine or dryer appliances and sends notifications for various events throughout the wash/dry cycle.
+
+## Features
+
+- Start notification with cycle duration, estimated end time, and mode details
+- Completion notification (reminder to unload clothes) with energy report
+- "Almost done" notification (configurable minutes before end)
+- Pause/Resume notifications (detect when cycle is paused or resumed)
+- Error message notifications
+- Preparation mode notification (e.g., for dryer prep)
+- Tub/drum cleaning reminder based on wash counter
+- Power consumption monitoring with energy tracking per cycle
+- Fully customizable notification messages (i18n support)
+- Debug notifications for troubleshooting
+
+## State Machine
+
+The automation tracks the appliance through these states:
+
+| State | Description |
+|-------|-------------|
+| IDLE | Waiting for cycle to start |
+| RUNNING | Cycle in progress (start notification sent) |
+| PAUSED | Cycle temporarily paused (pause notification sent) |
+| FINISHING | Near completion (time-to-end notification sent) |
+| COMPLETED | Cycle done (completion notification sent, state reset) |
+
+## Persistent State Keys
+
+| Key | Description |
+|-----|-------------|
+| `nass` | Notification About Start Sent |
+| `nart` | Notification About Remaining Time Sent |
+| `naps` | Notification About Preparation Sent |
+| `napas` | Notification About Pause Sent |
+| `wasp` | Was Paused flag |
+| `cst` | Cycle Start Time (ISO timestamp) |
+| `esmp` | Energy Samples accumulator (Wh) |
+| `lst` | Last Sample Time (ISO timestamp) |
+
+## Message Template Variables
+
+All message templates support these placeholder variables (use single braces):
+
+| Variable | Description |
+|----------|-------------|
+| `{appliance_name}` | Device name (e.g., "Washing Machine") |
+| `{remaining}` | Remaining time as string (e.g., "01:30:00") |
+| `{estimated_end}` | Estimated completion time (e.g., "14:30") |
+| `{minutes}` | Remaining minutes as number (e.g., 90) |
+| `{error}` | Error message text (only in error notification) |
+| `{tub_count}` | Tub clean counter value (only in tub clean notification) |
+| `{tub_threshold}` | Tub clean threshold (only in tub clean notification) |
+| `{details}` | Startup details from sensors (only in start notification) |
+| `{energy_kwh}` | Energy consumed in kWh (only in completion notification) |
+| `{energy_cost}` | Estimated cost (only in completion notification) |
+
+## Requirements
+
+- Sensors for: remaining time, run state, error messages
+- `input_text` entity for persistent state storage
+- Notification service entity
+- (Optional) Power sensor for energy tracking
+
+## Note
+
+Default messages are in Russian for LG ThinQ integration. Customize messages in the "Messages" section for your language.
