Log Message:

Add JSON wire format for task queue with gradual rollout support

Adds serialize/deserialize methods to DW::Task that support a new v2 JSON wire format alongside the legacy Storable format. This enables non-Perl consumers (e.g. Go workers) to read task queue messages.

$LJ::TASK_QUEUE_JSON controls the rollout as a float 0-1 (e.g. 0.01 = 1% of messages serialized as JSON). Default is 0 (all Storable). All consumers can read both formats regardless of this setting. If JSON encoding fails for a task (e.g. blessed objects in args), it falls back to Storable with a warning and stat tag identifying the task class.

Also adds task queue config documentation to config-local.pl.example and comprehensive test coverage for LocalDisk lifecycle, serialization round-trips, and queue_attributes.
