v0.7.2

Packaging and documentation only. No behaviour changed: every method keeps its name, arguments
and return shape, and no API or payment path was touched.

Changed

• The Composer package is p2flux/sdk-php and is published on Packagist, so installation is
  composer require p2flux/sdk-php — no repositories block and no VCS pin. The namespace,
  P2Flux\, and the PSR-4 layout are unchanged; the old name was never published anywhere.
• composer.json carries production metadata (keywords, homepage, issue/source/docs links) and
  composer test, which runs the whole offline suite.
• The README is a standalone entry point: install, requirements, a five-minute quickstart,
  configuration, the USDC-network-fee flow, error handling and links to everything else.
• The integration guide was split into one page per topic — docs/getting-started.md,
  docs/payments.md, docs/network-fee-in-usdc.md, docs/subscriptions.md, docs/refunds.md and
  docs/errors.md. docs/guide.md is now the index.
• Every example loads vendor/autoload.php and reads its configuration from the environment, and
  fails with the missing variable's name rather than a stack trace. examples/one-time.php is now
  examples/create-payment.php.

Added

• examples/verify-payment.php — server-side verification and the recoverPayment() fallback.
  P2Flux sends no webhooks; this is the trust boundary, and the documentation now says so plainly.
• tests/examples.php runs every example against tests/stub-api.php, a canned API on loopback,
  and tests/docs.php checks that every documented class, method, option and snippet still exists
  and parses. Both are offline and part of composer test.
• .gitattributes keeps the Composer dist archive to the library itself.

Install
