ci(deploy): let Vercel build main app

[RSO]

Summary

• Switch the main app production deployment from runner-built prebuilt artifacts to Vercel-side production builds.
• Apply the same behavior to the manual web redeploy workflow.
• Keep checkout and .nvmrc Node setup for the Vercel CLI, but remove runner-side dependency install, Next cache, Vercel pull, and local build steps.

Verification

• Confirmed the workflow diff only changes the deploy-app jobs in the production and manual redeploy workflows.

Reviewer Notes

• This follows the global-app rollout pattern after moving that lower-risk deploy path first.
• Vercel project build settings for kilocode-app must be correct because GitHub no longer runs vercel build for that project.

Executive Summary
