## Summary
Standardize the repo's Node contract on 24 while centralizing workflow
resolution through `.nvmrc` so local setup, CI, and package metadata
stay aligned from one version file.
## Changes
- **What**: Add `package.json` `engines.node = 24.x`, switch every
`actions/setup-node` workflow in the repo to `node-version-file:
'.nvmrc'`, and update contributor and Playwright docs to point to
`.nvmrc` as the Node source of truth.
## Review Focus
The workflow behavior should be unchanged apart from sourcing the Node
version from `.nvmrc` instead of repeating literals like `20`, `22`,
`24.x`, or `lts/*`. GitHub's formatter also moved the new `engines`
block to the package metadata section near the end of `package.json`.

## Summary
Adds automated npm publishing for @comfyorg/desktop-ui package with
version management and release workflows.
- Ref: #5912
## Changes
- **What**: Three GitHub Actions workflows for desktop-ui npm publishing
automation
### Two functions
1. Bump action - Just creates a version bump PR for `desktop-ui`
2. Publish action - Can be run manually - essentially a function with
params / void return
### One automation
- Watches for matching commits, then calls the Publish action with
pre-filled details
## Review Focus
Security hardening and workflow correctness.
