feat: deprecate globals, default noGlobals: true for new projects

- noGlobals: true skips ALL globals including Mocha DSL (Feature, Scenario, etc.)
- noGlobals: false (default for existing projects) prints deprecation warning
- New projects generated via `codeceptjs init` get noGlobals: true by default
- Store noGlobals flag in store so initMochaGlobals respects it
