V3 Ruby/RSpec test-run capability pack. By-value connector composition (service_kind=cli, no separate ingredient): one local bundle CLI ingredient exposes bounded project operations for RSpec readiness and test execution. Invocations run the project's bundled rspec command from one explicit project directory cwd supplied at execution time and return plain RSpec output via the ruby.test_run catalog operation. Fixed invocation, but approval-gated: RSpec loads project Ruby code, Rails initializers, support files, factories, mocks, and test fixtures, and may write project/database/cache state or contact services depending on the project. The pack uses the project bundle, progress formatter, no ANSI color, no caller-supplied spec path, formatter, tag, pattern, require, profile, seed, dry-run, bisect, env override, stdin, or shell wrapper. Test failures and RSpec diagnostics are represented as text results so the caller can inspect output. Requires bundle on PATH and rspec in the project bundle.
