Fix prepare scripts to avoid yarn deadlock during install

## Problem
The prepare scripts were calling `yarn run build` which caused a deadlock when triggered during `yarn install --frozen-lockfile`. This made the CI test job hang indefinitely.

## Root Cause
When `yarn install` executes the prepare lifecycle hook, it's still holding internal locks. Calling `yarn run` from within this hook tries to acquire the same locks, resulting in a deadlock.

## Solution
Replace `yarn run build` with direct command execution in all prepare scripts:
- `yarn run build` → `(rm -rf ./lib && tsc ...)`

This avoids the yarn deadlock while maintaining the same build behavior.

## Testing
- ✅ Clean install works: `rm -rf node_modules && yarn install --frozen-lockfile`
- ✅ Jest CI tests no longer hang: `yarn workspace react-on-rails-pro-node-renderer run ci`
- ✅ Build artifacts created correctly
- ✅ YALC publish works as expected
