--watch defaults to true globally, so `ns test <platform>` always resolved watch mode even when the flag was never passed. For Vitest projects this printed a spurious "'--watch' is not supported" warning on every run, and for Karma projects it kept the process alive in CI instead of exiting after a single run. The test commands now declare their own --watch default, disabled when a CI environment is detected (CI/JENKINS_HOME). Explicit --watch and --no-watch still take precedence, and local behavior is unchanged.

…itly Watch mode defaults to on outside CI, so checking $options.watch printed the unsupported-watch warning on every local Vitest run. Also document JENKINS_HOME alongside CI in the --watch man page entries.

- Line 50: Update the watch-mode warning condition in the Vitest execution
service to use both the explicit --watch option and the parsed $options.watch
value, so --watch false does not warn while --watch=true does. Add tests in the
Vitest execution service tests covering both forms.

Handle --watch=true and --watch false/--watch=false, not only a bare --watch.
