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.

+# diigo-week
+
+An EmDash plugin that drafts a potluck issue from a week of your shared diigo bookmarks. It reads them as microformats from diigo-cache's public page, so you edit a draft instead of copy-pasting links.
+
+## Getting started
+
+Run diigo-cache (with a filled public cache) and potluck, each in its own terminal:
+
+```sh
+pnpm install
+(cd ../diigo-cache && pnpm dev)   # → http://localhost:8787/
+(cd ../potluck && pnpm dev)       # → http://localhost:4321/_emdash/admin
+```
+
+In potluck's admin: Plugins → **Draft from diigo** → **Draft issue**. The draft shows up under Issues.
+
+## How it reads the week
+
+It asks diigo-cache for `/public/<user>?in=<week>&by=created` over the `DIIGO_CACHE` service binding (potluck's `wrangler.jsonc`), reads the page's `h-feed` of `h-entry` bookmarks, follows `rel=next`, and creates a draft in `issues`: title, week, dek, and a paragraph per bookmark with its description and tag links, as in potluck's `seed/issues.json`. The binding is its only reach outside the site; it declares `content:write` and `taxonomies:write` (the issue gets its bookmarks' tags, as the sample issues do), nothing else.
+
+Checks: `pnpm lint && pnpm test`.
