Root cause: both attach_generated_images() in post-assembler and the
retroactive handler in executor passed null as source_data to the image
pipeline. The pipeline's Image B branch requires non-null source_data
to fire, so Image B was silently skipped on every article since the
feature was built.
Fix: added get_source_data_for_image() to Source_Collector to retrieve
the original Reddit post title/content by source_ids. Post-assembler
now pulls source_ids from the Article_Idea; executor pulls them from
the _prautoblogger_source_ids post meta saved by the publisher.
Also added a regression test proving Image B is skipped when source_data
is null, so this handoff gap will be caught if re-introduced.

Taxonomy assignment, generation log linking, LLM content sanitization,
default author resolution, and image pipeline attachment moved to
PRAutoBlogger_Post_Assembler as static helpers. Publisher retains
create_post orchestration, publish/draft flow, and meta building.
