fix: move vite from dependencies to devDependencies

[smoreinis]

Summary

• Moves vite from dependencies to devDependencies since it's only used for testing (vitest) and not needed in production

Test plan

• Run npm run build to confirm production build still works
• Run npm test to confirm vitest still works

Greptile Summary

Moves vite from dependencies to devDependencies in the agentex-ui package. This is a correct categorization since Vite is only used as the engine for Vitest (test runner), while the production build uses Next.js (next build). The Dockerfile already uses npm ci --omit=dev, so this change will reduce the production Docker image size by excluding Vite and its transitive dependencies (esbuild, rollup, etc.).

• Moved vite@^7.3.1 from dependencies to devDependencies in package.json
• Updated package-lock.json to mark vite and all transitive dependencies as dev-only

Confidence Score: 5/5

• This PR is safe to merge — it correctly recategorizes a build/test tool as a dev dependency with no impact on production behavior.
• The change is minimal and well-scoped. Vite is only referenced in test configuration (vitest.config.mts) and test files, never in production code or the Next.js build. The Dockerfile already uses --omit=dev, confirming this aligns with the existing production build strategy. The package-lock.json changes are mechanically consistent.
• No files require special attention.

Important Files Changed

Filename	Overview
agentex-ui/package.json	Moves vite from dependencies to devDependencies. Correct change since Vite is only used via Vitest for testing and the production build uses Next.js.
agentex-ui/package-lock.json	Lock file updated to mark vite and its transitive dependencies (esbuild binaries, rollup, tinyglobby, fsevents, etc.) as dev: true. Changes are consistent with the package.json update.
