Daily cron val that watches Anthropic's Singapore office openings and emails the val owner whenever a role is added or removed.

Anthropic's careers page is a client-rendered app backed by Greenhouse, so instead of scraping HTML we query Greenhouse's public job-board API:

https://boards-api.greenhouse.io/v1/boards/anthropic/offices

singapore_jobs.cron.ts:

1. Fetches all offices, picks office 4063231008 (Singapore).
2. Flattens its departments into a list of { id, title, department, location, url }.
3. Loads the previous list from blob storage (anthropic_sg_jobs_v1).
4. Diffs by job id:
   • First run → saves a baseline and sends a one-time "now watching" email.
   • Changes → saves the new list and emails the new/closed roles.
   • No changes → does nothing.

Email goes to the val owner via std/email (no recipient config needed).

1. Push to Val Town: vt push
2. In the Val Town UI, set the cron schedule to run daily (e.g. 0 9 * * * for 9am UTC).
3. Use Run in the UI to trigger it once — the first run saves the baseline and sends a confirmation email.

• Different office: change OFFICE_ID / OFFICE_NAME (find IDs via the /offices API above).
• Reset the baseline: delete the blob key anthropic_sg_jobs_v1; the next run re-seeds it.
