fix: Mark comfy-api-plugin as build-time only (#8224)

## Summary

Marks the `comfy-api-plugin` Vite plugin as build-time only by adding
`apply: 'build'`.

This prevents the plugin's transform from running during development
(`vite dev`), improving dev server startup time and avoiding unnecessary
processing when the plugin's output is not needed in development mode.

Also updates `build/tsconfig.json` to use `moduleResolution: "bundler"`
which is the recommended setting for Vite projects.

## Changes

- **build/plugins/comfyAPIPlugin.ts**: Add `apply: 'build'` to restrict
plugin to production builds
- **build/tsconfig.json**: Update `moduleResolution` from `"node"` to
`"bundler"`

## Testing

- `pnpm typecheck` passes
- `pnpm build` produces correct output
