Subject: [PATCH] Prepare Gradle build scripts for Gradle 10

Gradle 9.6.1 deprecates the Kotlin DSL property-delegate syntax (removal in
Gradle 10):
- `val x by tasks.registering { }`  -> `val x = tasks.register("x") { }`
- `val x: String by settings`        -> `providers.gradleProperty("x").get()`
- `val x: String by project`         -> `providers.gradleProperty("x").get()`

Switch the task declarations in hello-xtc and the localOnly property reads in
settings.gradle.kts / hello-xtc/build.gradle.kts to the recommended APIs,
matching xtclang/xvm#494. localOnly is always defined in gradle.properties, so
.get() preserves the previous fail-fast behavior.

Verified: `./gradlew build --warning-mode fail` is BUILD SUCCESSFUL with no
deprecation warnings.
