v1.0.0

First stable release.

• Laravel 13 support (illuminate/* now ^10|^11|^12|^13).
• Depends on solution-forest/workflow-engine-core: ^1.0 instead of dev-main || ^0.0.3-alpha. A stable release cannot require an alpha, and dev-main in a release means consumers get whatever main happens to be that day.
• minimum-stability is now stable.

The test suite had never run against core 0.0.4+, and three things had drifted:

• Auto-generated step ids became 1-based in core, so assertions on email_0 / http_0 / delay_0 were off by one. Two tests also asserted the same key twice while claiming to check three different steps, which hid it.
• WorkflowContext is immutable now and setData() is gone; a fixture still mutated the context it was handed.
• One test made a real HTTP request to api.example.com and a real five-minute delay — it spent 300 seconds sleeping, then failed on DNS, and never reached the payment assertions that were also broken.

Suite time: 304s → 4.6s, 74 tests passing.

Note: workflow-engine-core v1.0.0 is not yet on Packagist — the repository has no Packagist webhook configured. Until it is published, consumers need a VCS repository entry for the core package.
