Adds “ignored regions” highlighting support to the addon by introducing preview-side annotations/decorators, a manager toolbar toggle, and packaging/build updates to ship the new preview entrypoint.
Changes:
- Add preview annotations (
src/preview.ts) that can highlight elements matching ChromaticignoreSelectorsand emit a count to the manager. - Add a manager toolbar control (
GlobalIgnoreToggle) and manager-side click handler to open docs for ignore configuration. - Extend build/package configuration to compile and export the preview entrypoint.
