Lifts the build off the JDK-21 ceiling — the old AGP 8.7.3 pin could not run
on JDK 25. Two AGP-9 migration edits were required:
- AGP 9 ships built-in Kotlin support, so applying org.jetbrains.kotlin.android
alongside it fails with "extension with name kotlin already registered";
the alias is dropped (kotlin.compose / kotlin.serialization stay, they are
separate compiler plugins).
- kotlinOptions { jvmTarget } came from that plugin and no longer resolves;
AGP derives jvmTarget from compileOptions instead.
compileSdk/targetSdk 35 -> 36, since Android Studio ships API 36.1 by default
and installing 35 was avoidable churn. versionCode 5 so the reports from this
toolchain are attributable (build 4 was already archived from the old one).
Also fixes a missing comma that left .claude/settings.json invalid JSON.

Monorepo root for Echolot. Contains the no-root capability prober
(Kotlin/Compose, app.echo_lot.prober) and the four design docs that act
as the contract for the production app and the Go server.
LICENSE is deliberately absent — still undecided, see docs/build-status.md.
