Daily cron val that:

1. Fetches recent topics and posts from the n8n forum "Questions" category.
2. Summarizes the discussions (last 24 hours) using OpenAI.
3. Emails the digest to you.

Set these in Val Town Secrets if needed:

Optional:

• OPENAI_MODEL: OpenAI model name (default: gpt-4o-mini).
• OPENAI_API_KEY: If you are using a custom OpenAI integration. By default, it uses Val Town's standard OpenAI helper.

• The val fetches the top topics in the "Questions" category via the Discourse JSON API.
• It filters for topics that had activity (new posts) in the last 24 hours.
• For each active topic, it fetches the first post (to get the context of the question) and any posts made in the last 24 hours.
• It passes this content to OpenAI for summarization, following the same format as discordDailyDigest.
• Finally, it sends an HTML email with the summary.

• This val uses the public Discourse API and does not require forum credentials.
• It targets category 12 ("Questions").
• On Val Town Free, the v/std/email helper only emails the account owner.
