Pull request overview

Updates the All Contributors configuration to reflect additional contribution categories for @proflead, aligning their entry with contributions from merged PR #1266.

Changes:

• Expanded @proflead’s contributions list to include code and content in addition to agents.

Just need to run npm run contributors:generate so that it updates the README and website with the new attributions.

[proflead]

I ran npm run contributors:generate locally, followed by npm run build and bash eng/fix-line-endings.sh. The commands completed successfully, but they produced no additional diff. README.md and website/src/pages/contributors.astro already contain the existing @proflead contributor entry, and the current all-contributors template renders only the avatar/name cell, so adding code and content only changes .all-contributorsrc.
