Add Java TestNG emit kit

[TSavo]

Summary

• add provekit-emit-java-testng as a separate Java emitter artifact
• register java-testng through project config and emit manifest
• emit native TestNG source using org.testng.annotations.Test and org.testng.Assert
• report unsupported predicates with incomplete status
• add Rust CLI integration coverage for config/manifest/RPC dispatch only

Verification

• mvn -B -ntp -pl provekit-emit-java-testng -am package
• cargo test -p provekit-cli --test cmd_emit_java_testng --manifest-path implementations/rust/Cargo.toml emit_java_testng_dispatches_real_emitter_and_maven_checks_output -- --nocapture
• cargo fmt --manifest-path implementations/rust/provekit-cli/Cargo.toml --check
• git diff --check

Note: Maven prints the existing reactor warnings for provekit-lift-java-term-shape and the normal shade MANIFEST overlap warning; the build passes.

Generate placeholders that satisfy executed TestNG assertions

When a plan contains supported predicates beyond the all-zero cases, these per-variable defaults make the emitted TestNG methods fail at runtime even though the emission reports is_complete: e.g. ne, lt, and gt declare both operands as 0, option-is-some/not-null declare Object ... = null, and fallible-err gets a non-throwing null value. Since this kit's compile check actually runs mvn -q test in RpcServer.checkResult, provekit emit --compile-check fails for contracts the plugin advertises as supported; the placeholders need to be chosen per predicate/argument (as the other emitters do) or these predicates should be left unsupported.
