2.2.0-dev.4 — ATF validation fixes

Fixes ATF suite membership validation, duplicate-ID errors, suite-name listing with reference objects, and readiness checks for missing references and empty active tests.

Validated with 1,616 unit tests, 250 protocol checks, 72 profile checks, 14 release checks, and live Global-scope regressions on the fd demo instance. Temporary fixtures were removed.

Install: npm install -g @onlyflows/servicenow-mcp@dev

Cloud execution remains browser-free locally. Positive UI workflow validation is still blocked by the demo instance's proActiveTrigger page error. The optional container validation job retains its existing exit-code-13 failure; required npm release checks passed.
