v0.22.3

Added

• chunky.assembly.connection — the assemble job's queue connection is now configurable via CHUNKY_ASSEMBLY_CONNECTION, mirroring the existing chunky.assembly.queue knob. Set it to sync to run assembly in-process (no queue worker required) — useful for dev environments, small uploads, or apps that don't run a worker — without flipping the global QUEUE_CONNECTION and forcing every other queued job in the host app onto sync. A named connection from config/queue.php (e.g. redis-uploads, sqs-large-files) routes just the chunky assembly off the default queue. null (default) keeps the previous behaviour: the job uses config('queue.default'). Six regression tests cover the default / explicit / empty-string / queue + connection combinations and the existing tries / backoff / timeout wiring.
• Configuration reference gained an explicit Assembly job section in docs/configuration.md documenting the full chunky.assembly.* namespace, plus two new recipes: "Synchronous assembly (no queue worker)" and "Dedicated upload queue".
