OpenCode 0.4.6

The demo browser launcher now returns opened: false when the platform opener is missing, exits unsuccessfully, or does not confirm success within five seconds. Asynchronous spawn errors, including errors after the deadline, are handled without terminating the plugin host.

Validation: typecheck, 44 offline tests, build and package dry-run passed. Distribution remains through this immutable GitHub release. The package remains private and npm publication stays blocked.
