refactor: move CLI to orchestrator, fix validate-orchestrator workflow

- Delete src/cli.ts, src/cli/ (commands, tests, input-mapper) — moved
  to game-ci/orchestrator repo (PR #813 reference)
- Delete .github/workflows/release-cli.yml — moved to orchestrator
- Remove bin, pkg, yargs, @types/yargs, pkg from package.json
- Fix validate-orchestrator.yml:
  - Build TypeScript before running require() smoke tests
  - Remove || echo fallback that swallowed errors
  - Add smoke test that installs orchestrator via npm pack and
    verifies loadOrchestrator() returns defined exports

Legacy src/model/cli/ (Cli class, CliFunctionsRepository) preserved —
used by Input.getInput() and build-parameters.ts on main.
