v0.6.2

Added

• Blink.put_context/2,3 and Blink.put_table/2,3,4 for building a seeder directly from data that is already available, without a context/2 or table/2 callback. The /2 forms take a keyword list to add several keys/tables at once (e.g. put_context(user_id: id, project_indices: idx)); put_table/4 forwards per-table options (e.g. :batch_size, :max_concurrency). All are imported into modules that use Blink.
• Added the Providing Data Directly guide.
