Php85 support

[vedavith]

What changed

• Set Composer package name to vedavith/pops-fork, added support links, and credited the original author while adding maintainer info.
• Updated README to note this is a maintained fork and point installs at vedavith/pops-fork.
• Raised PHP support to 8.2+ with native type hints across proxies/tests; removed deprecated ReturnTypeWillChange usage.
• Added drop-in replace for eloquent/pops.
• Adjusted PHPUnit/coverage config for PHPUnit 11+; CI now runs PHPUnit directly with coverage and Codecov upload.
• Added dynamic PHP resolution (removed platform pin) and relaxed PHPUnit constraints (^11.3 || ^12).

Why

• Establishes the maintained fork identity and Composer metadata for Packagist.
• Ensures compatibility with PHP 8.2–8.5.
• Fixes CI failures around missing phpunit binary and deprecated flags.

Notes

• PHPUnit 11 runs on PHP 8.2; PHP 8.3+ can use 12.x.
