refactor(ci): Create reusable lint workflow and define dependencies

Creates a new reusable workflow, 'lint.yml', to handle all linting operations.

The main 'orchestrator.yml' is updated to use this new workflow. The dependency chain is now explicitly defined: 'lint' runs first, followed by 'build-and-publish' and 'ci' in parallel. The 'e2e' job remains dependent on 'build-and-publish'.

This change also removes the now-unused 'version' input from 'ci.yml' and corrects the 'bundle_size' job to use 'npm ci'.
