[WIP] 赤外線測距モジュールでとびらの開閉状態を見るように

[OJII3]

• feat: optimise voltage to distance conversion

センサの扱いについて

• 距離が近すぎると測れないので、センサの位置を工夫して、5cmくらいの状態を「閉じている」状態として扱うことにする。
• 電圧-距離変換は適当な変換テーブルを用意して変換しているが、データシート上にかかれているグラフより出力電圧が半分ほど低い模様。
• このACDCコンバーターは出力電圧を２チャンネル読めるが、チャンネル０を使用している

Pull Request Overview

This PR integrates an IR distance sensor (SHARP GP2Y0A21YK0F + MCP3002) into the door lock system to detect door open/close state and trigger auto-lock when the door closes.

• Add a new distance_sensor module implementing DoorSensor and calibration logic
• Extend domain traits (DoorSensor, DoorLock) and inject sensor into TouchCardUseCase
• Update main.rs, infra, and documentation to wire up the sensor and auto-lock flow

docs/door_sensor_setup.md:47

• The example uses new(1, 30.0), but the current API provides new() (default) or new_with_config(...). Please update the sample to match the actual constructors.

    let sensor = Gp2y0aDistanceSensor::new(1, 30.0)?;

crates/app/src/main.rs:71

• The comment states a 30cm threshold, but new() uses a 5cm default threshold (DOOR_SENSOR_THRESHOLD_DISTANCE). Please update the comment or use a custom config to align with expectations.

    let door_sensor = Gp2y0aDistanceSensor::new()?; // チャンネル0、閾値30cm
