Subject: [PATCH] feat: use minified builds for bundle size comparisons

Add build:minified scripts that enable minification during builds,
and configure the compressed-size-action to use these scripts.

This ensures that bundle size measurements in PRs reflect actual
code changes rather than being inflated by comments and whitespace,
while keeping the published packages readable and unminified.

Changes:
- Add build:minified script to root package.json
- Add build:minified scripts to @tanstack/db and @tanstack/react-db
- Configure compressed-size-action to use build:minified script
