Pull request overview

This PR removes the Stencil-based React proxy generation path for Atomic, and relies on the Lit/@lit/react-based wrapper generation instead. It also cleans up now-unneeded dependencies, patches, and build scripts tied to the Stencil React output target.

Changes:

• Remove @stencil/react-output-target usage from packages/atomic/stencil.config.ts and drop the dependency/patches.
• Stop re-exporting Stencil-generated React bindings from @coveo/atomic-react entrypoints (search/commerce/recommendation).
• Simplify @coveo/atomic-react build scripts by removing the import-path “fixup” steps and the fix-esm-import-path dependency.
