fix: update hidden dependencies and add @handlebars/parser to package configuration

- Added @handlebars/** to the list of exposed dependencies in rollup.config.mjs.
- Updated the resolution path for @handlebars/parser in hiddenDependencies function.
- Created a .gitignore file for the @handlebars/parser package to exclude dist/ and lib/parser.js.

Simplify the handlebars/parser build and add it in to to the set of things we build in the root package.josn

lint:fix
