Upgrade to 1.0.0-rc757

Concerns: pushword/core, pushword/dev-app

pushword/skeleton renamed to pushword/dev-app

The demo/test/installer package pushword/skeleton has been renamed to pushword/dev-app — it never was a copy-paste skeleton (the installer is the real starting point), so the name was misleading. pushword/core requires it, so every install pulls it into vendor/ transitively.

For almost everyone: nothing to do. A plain composer update resolves the new pushword/dev-app automatically through pushword/core and drops the old pushword/skeleton. The old package is no longer maintained.

Only act if one of these applies to your project:

• You require pushword/skeleton explicitly in your own composer.json (rare — the installer removes it): replace it with pushword/dev-app.

  composer remove pushword/skeleton 2>/dev/null; composer require pushword/dev-app

• You reference the vendor/pushword/skeleton/… path in scripts, CI, config or docs: update it to vendor/pushword/dev-app/….

  grep -rl 'pushword/skeleton' . --exclude-dir=vendor | xargs -r sed -i 's#pushword/skeleton#pushword/dev-app#g'

Then composer update && php bin/console cache:clear.
