Auto-summarize New/Updated Bills

[Mephistic]

Problem

When a new bill is added or the text of an existing bill is updated, any LLM-generated bill summaries will become (potentially) out-of-date. To keep our LLM Bill Summaries relevant, we should automatically generate a new summary whenever a bill is added OR a bill's text is updated.

(This is intentionally not an explicit ask for the first pass to be extra cautious with our LLM credits during the initial churn of the model generation - we want to be extremely careful that we cannot end up in a loop where we erroneously generate new summaries each time we scrape a bill, and the surest way to be resilient to that error is to keep the summary generation outside of automated paths at first).

Success Criteria

• Whenever a bill is newly added OR a bill's text is updated, queue up a request to generate a new bill summary
  • We should add a hard limit on the number of times a bill can have a summary generated (updates to bill text are infrequent, as should be updates to the model after the initial development - we want to cap the potential impact of a bug that triggers an infinite summarization loop).
  • At the start of a new session, we will likely get a batch of thousands of bills added over a very short period of time - we may want to consider introducing jitter to the summarization requests at minimum, and potentially a temporary queue for summarization requests that a longer-running cloud function could poll. Summaries don't need to be generated with particular speed, as long as we keep things relatively up-to-date.
