diigo-week: draft a potluck issue from a week of diigo bookmarks

An EmDash plugin (native, content:write only) with one admin page:
a diigo username and an ISO week. It reads diigo-cache's public page
(?in=<week>&by=created) as microformats, follows rel=next, and
creates a draft in issues shaped like seed/issues.json.

Transport is a DIIGO_CACHE service binding rather than ctx.http.fetch:
EmDash's SSRF guard refuses localhost, and the binding names one
worker. Logic lives in src/week.ts with the fetcher passed in; tests
read fixtures in diigo-cache's markup. The checklist's goal 2 now
names potluck; DiigoBridge waits.
