Description

After upgrading from Laravel 12.28.1 to 12.29.0, my uncompressed application size increased by ~13 MB. This caused my Vapor (Lambda runtime) deploy to fail because AWS Lambda enforces a 250 MB unzipped size limit (code + layers).

I traced the increase to the new local debug page introduced in 12.29.0. This page pulls in the phiki/phiki package, which includes syntax highlighting grammars and themes. In my vendor directory, phiki alone takes ~13.2 MB uncompressed.

While this is not an issue for most deployments, on Vapor/Lambda environments the additional size is enough to push some applications over the AWS limit.

Steps To Reproduce

1. Create a fresh Laravel 12.28.1 app and install dependencies.
2. Check uncompressed size of vendor directory: well below Lambda's 250 MB cap.
3. Upgrade to Laravel 12.29.0.
4. Observe that phiki/phiki is installed (~13 MB uncompressed).
5. Attempt to deploy to Vapor (non-Docker Lambda runtime).
6. Deployment fails with error: "Function code combined with layers exceeds the maximum allowed size of 262144000 bytes."

I've opened a PR to remove phiki/phiki and replace it with shiki to handle syntax highlighting on the frontend.
