Blueprint.phar PHP 7.0 compat

[adamziel]

Makes the built Blueprint.phar file compatible with PHP 7.0:

rm -rf examples/new-wp;
make bundle_web;
USE_PHAR=1 php examples/blueprint_compiling_simple_progress.php
# It starts downloading and extracting WordPress etc

# Also, try
docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp php:7.0-cli php your-script.php
# It starts downloading and extracting WordPress etc

Changes made

• Added a Makefile to manage two separate dependency environments: dev and web (for building the .phar)
• All dependencies brought over to this repo and patched for PHP 7.0 – 8.3 compat
• Cleaned up the .phar contents to reduce the size to ~180KB
• Allow calling wp-cli commands as root for the docker run use-case above. TODO: Revisit, maybe add a special --allow-root mode to the entire Blueprints library.
