Packaged desktop sidecar crashes at first DB read: jlink image omits java.sql

desktop-sidecar/build.gradle.kts を開いて nativeDistributions ブロックを確認し、Issue に記載された ./gradlew createDistributable とパッケージ化された AgentTaskQueueSidecar コマンドを使って再現します。パッケージ化された sidecar が java.sql.Driver の ClassNotFoundException なしで最初のデータベース読み取りを完了すれば完了です。

Summary

The packaged desktop sidecar produced by the README's documented package path (./gradlew packageDistributionForCurrentOS, or createDistributable) crashes on its first database read with ClassNotFoundException: java.sql.Driver. ./gradlew run is unaffected because it runs on the full JDK.

Environment

• macOS 15 (arm64), Temurin JDK 21.0.12
• repo at ccb94ae25c2b286d62e7371fd4c0f7ce60e33efa

Reproduce

cd desktop-sidecar
./gradlew createDistributable
./build/compose/binaries/main/app/AgentTaskQueueSidecar.app/Contents/MacOS/AgentTaskQueueSidecar --data-dir /tmp/atq-repro

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: java/sql/Driver
	at com.block.agenttaskqueue.sidecar.TaskQueueDatabase.<clinit>(TaskQueueDatabase.kt:10)
	...
Caused by: java.lang.ClassNotFoundException: java.sql.Driver

Cause

desktop-sidecar/build.gradle.kts's nativeDistributions block declares no modules(...), so the jlink runtime image omits java.sql even though the project depends on org.xerial:sqlite-jdbc (3.53.0.0), which needs it at class-load time.

Fix

One line in the nativeDistributions block:

modules("java.sql")

Happy to send the one-line PR if that's easier.
