Ignition 8.3 runs on JDK 17; the 0.1.2 client was compiled --release 21 (class-file v65) and would throw UnsupportedClassVersionError when loaded in an Ignition module. Drop the toolchain and bytecode target to 17 so the artifact loads on the gateway (a 17 build still runs on 21+). No source uses Java 18-21 APIs, so this is a pure target change. Bump 0.1.2 -> 0.2.0. Update the toolchain-pinning smoke test to assert feature()==17. All 97 tests pass; all jar classes verified class-file v61. Roadmap G0.
