V3 generic project test-run capability pack. By-value connector composition (service_kind=cli, no separate ingredient): one local make CLI ingredient exposes bounded project operations for readiness and fixed-target test execution. Test runs execute the fixed test target from one explicit project directory cwd and return plain make output via the project.test_run catalog operation. Fixed invocation, but approval-gated: Makefiles can execute arbitrary project commands, compilers, scripts, containers, network clients, and test code, and may write project or cache state. The pack exposes no caller-supplied target, variables, makefile path, directory flag, job control, environment override, stdin, or shell wrapper; it runs exactly make test in the declared cwd. Test failures and make diagnostics are represented as text results so the caller can inspect the output. Requires make on PATH.
