feat(diigo-dump): session-cookie dump worker, manual test passing

Port of mm-diigo/projects/diigo-bak/diigo-dump.mjs as a Cloudflare Worker:
one page-number field + button, GET interact_api/load_user_items
(sort=updated, count=24) with DIIGO_COOKIE as a Worker secret.
GET / is inert; dumps happen only on POST submit.

Manual integration testing (local wrangler dev, port 8788, 2026-10-06)
shows it works: status 200, total 1674 bookmarks, page-1 items returned.
The browser-session-cookie path authenticates; the static API-key path
(diigo-ping worker, EmDash plugin) is still rejected by Diigo (401).

Also: project checklist (capsite-checklist.md) with step results, and a
.gitignore for local artifacts (.dev.vars, node_modules, wrangler state).
