Pull request overview

This PR adds Symfony Web Profiler (debug bar) integration to expose the bundle’s resolved Encore entry points and registered extensions during a request.

Changes:

• Persist the resolved EntryPoints on the current request (encore_entries) so the profiler can read them.
• Add a Symfony data collector (EncoreCollector) and a Web Profiler panel/toolbar template to display entries/extensions.
• Add a small README header icon (SVG) for branding.
